Hi Guys,

I have been looking into the King Gun Sight Co, and other related shops, such as Micro Sight Co, in my interest in mid 20th century Bullseye revolver custom work, specifically as carried out on the wonderful K and N frame S&W revolvers we all know and love.

While the products and services offered by King are fairly well documented in all their variations and glory, few are aware that there were other competing firms. One of these was the Micro Sight Co., which was incorporated on April 24, 1947 (supposedly by one or more former King employees!).
No doubt many of you are aware of Micro as being the makers of the rear sight used on many of the Old Model Ruger Blackhawks. (How brilliant of Bill Ruger. He was basically offering what amounted to a custom revolver with everything many folks dreamed of!)
However, Micro did a lot of custom work on revolvers, as well! This work included installing their own design of click adjustable rear sights, ramped front sights with Baughmann or Patridge profiles, action work, and customizing hammers to "cockeye" configuration.

As it turns out, it was the latter work that got them into hot water, legally speaking. A lawsuit was filed in the U.S. Court of Appeals for the Ninth Circuit by King against Micro in January 1955. The lawsuit had four points, but mainly claimed of copyright infringement of the term "Cockeyed" hammer. One other significant claim of the suit was unfair competition. It was claimed that an employee of King's was also in the employ of Micro, and was diverting business from the former to the latter, specifically involving the fabrication and installation of cockeyed hammers.

However, the point likely of most interest to S&W aficionados and collectors is probably that of the "Cockeyed" hammer trademark and patent. King's claimed ownership of both, through U.S. Pat. #2,159,527 and a Jan 11, 1938 trademark certificate of registration #353691.
Legal representatives of Micro argued that the development of the cockeyed hammer could actually be traced back earlier to a Diefendorf-O'Toole innovation going back to 1935. In the course of the trial, other patent drawings, two going back to the late 19th century, were produced that pre-dated the King patent.

Micro prevailed in court on three of the four counts, and furthermore, the court ruled both King's patent and trademark registration as invalid.

The court also ruled that each party was responsible to bear their own legal costs.
Lawsuits of this type were surprisingly common at this time amongst partnerships and competitors in the gunsmithing world. Think of the time and money this must have diverted from their businesses.
On this point, I guess this might be a contributing factor in why both King and Micro eventually just quietly went away.

I hope this is of some interest....

Best Regards,
Jim

Very interesting .I had heard years ago talk of the King lawsuit but I never heard how it turned out.I always thought companies like king ,micro ect would sell their ideas to a major manufacturer and eventually the big dog eats the little dog . I guess sometimes the little dogs eat each other.
 
If you look into the Bomar, Triangle, King, Micro sights of the post-War era, you will see lots of similarities, especially those for the Government Model, but probably to a lesser degree on revolvers. IIRC, there was a big court fight between Bomar and Triangle.

We’re in great times for finding good sights, grips, etc, but the ‘50s also offered some great opportunities, the results of which are now most highly desirable.

When D.W. King died in 1944 there apparently was quite a struggle over the business. His widow hired a man that alienated the existing employees, most of whom left the company. Some of them started Micro and probably misappropriated intellectual property that belonged to King. Others just took lots of parts and started their own gunsmithing business, e.g. Bob Chow. Eventually Mrs. King licensed the patents to Ricky Gun Sight company (named for one of the founder's sons).

I have found while some of Micro's work was nice they were not up to what I have found on most King work.

Here is an example of Micro's try at a rib.

Held this at a show. Felt like holding a brick. Very poor sight picture.

Very interesting!
So, for that price the seller had misidentified who did the custom work? Hmm. Of course, the King name was probably good for a few extra bucks on that price tag!

He didn't see the small Micro ID, I think many now would be unaware of Miro or King, but does makes me very happy when going to this particular gun show.

I think the rib was steel,unlike what King was using.
 
I have a micro sighted Colt that I am happy with. (Very happy, also a .22lr Christy conversion).

I also have an early (clearly patent infringing) Micro modified k22 outdoorsman that I am less then pleased with due to the bluing.

[picture omitted due to this gun being my secret shame of overpaying before understanding what a bad reblue actually meant]
 
My Micro sighted .455 conversion

I assumed this British proofed .455 reamed to .45LC was the work of some random gunsmith.
Since it wears front and rear Micro sights and a shop-welded Cockeyed hammer, maybe it was done at Micro. Who knows.

I picked it up somewhat cheap ($350) to have fun with or use for a future project. I guess I'll clean it up and put some decent custom stocks on it.

I can tell you that my microsight looks just like a King. The only difference being that they elctro-penciled MICRO on the side of it.

It's such an exact match for the King in fact that if it didn't have Micro on it, I would have assumed it was done by King. The lawsuit was clearly warranted.

I don't know that Micro didn't do yours for certain, but I would wager that your gun was some random gunsmith who bought Micro sights.
 
Many early Ruger Mark I target pistols were factory-equipped with Micro sights. I own a couple of them. This one with a 6 7/8" barrel is a duplicate of one I used to shoot on an Army pistol team, except that one was marked as government property.

I have the exact same Ruger pistol, except mine does have the "U.S." stamp.

I very much agree on the cockeyed hammer observation. I think they were practically identical to kings version. I do see on ocassion where the hammer is not marked at all.
 
Here’s a Micro Modified gun, a 44 Transitional I found at a gun show. As you can see, it’s a fairly nice modification . Maybe not on par with Kings, but still nice.

Hi Paul,
Thanks for posting those great pictures, especially the close-ups. That is surely one special .44!

That is a handsome SAA. Thank you for sharing. Is the front sight ramp notched? The low cut profile of the front blade looks very sleek. And, all set off with nice aged stag grips!

Yeah, guessing whoever had the work done at Christy (who I would imagine put the sights on it after they were supplied my Micro), killed many critters with it.

The notches appear to be ranges. I haven't yet figured out what they mean yet. All I know is that I really like shooting it. When I get my range properly ventilated it's at the top of my list for putting a lot of rounds through.

It's very heavy, perfect trigger, and the sights are quite good.

The grips are actually old Jigged Bone. I'm not sure why I like the stuff so much, but I'm just nuts for really old jigged bone.

The ramp base looks like the standard Micro base, but with the notches added. Is there any sort of vertical line or marking? Are the notches lined in white, or the like, to make them more visible?

What is the chambering?

Jigged Bone... yes, when you wrote that, it reminded me of knife scales. I kinda thought that Stag was not right as I was typing it, but I just had some brain freeze.
I'm guessing it was reblued at some point? Looks better than factory, for sure!
I just don't see enough of SAAs that have been worked on that look so right. Definitely nicer (in my book) than the old Harold Croft re-works.
(Not a fan of the New Frontier, either!)
From the bolt notches and very faint cylinder line, it looks like it's either hardly been shot, or it's been tuned to perfection.

Thanks again,
Jim
 
All the guns up on this thread are pretty nice ,it is great to see some of y’alls guns other that the S&Ws .This has truly turned out to be a very interesting and enlightening thread thanks to sixgunstrumpet admitting to overpaying for her k22 with poor reblue.Up until now I thought you folks were all born knowing this stuff and I was the only dummy that had to watch out .
