There's 2 different 'series' of 2nd generation Colt percussion pistols
C series 1971 to 77/78
F series 1978 to 82
The C series only had 2 models in it the '51 Navy and the 3rd Model Dragoon. There were plenty of special order, one-of's, ect made up in the Custom Shop at Colts on these as well.
Ser#'s picked up where old production left off.
Much has been knocked around about where the parts came from and who finished them, who assembled them ect.
It's not like it's ancient history,,those people are still very much with us that worked on that project.
The frames were investment cast in the USA and you can see that were investment cast by looking at the interior of any of those frames of a stripped down revolver.
I've been told that Ruger/Pine Tree Castings in NH made the frames. It's just business, and very common in the industry. You make what I need and can't make.
Marlin made Rugers bbls when Ruger was getting started.
The other pistol parts came from Uberti but through Navy Arms. N/A was the US contact for Uberti so Colt had to go through them for the major parts.
Steel parts finished machined, brass as cast. All fitting, assembly & finishing done in the US.
The F series is a different story as it has 10 or 12 models in it.
Plus the story muddles as to who was involved in the mfg'r with involvement of IverJohnson in it and it's owner Lou Imperato. Some versions place him & IJ in the C series mfg circle also.
All very confusing to say the least. I think the F series were for the most part finished and assembled by Iver Johnson,,but I don't know that for a fact. That's just my feeling from talking with some people in the business over the years.
It doesn't alter the fact that some parts were sourced from Uberti in Italy and finished and assembled in the USA to make the revolvers.
They are still considered a 'Colt'.
One thing I haven't been able to find is if the case coloring was done at Colt or outside the factory on the 2nd Gen Percussions.
Most all the 2nd and most of the 3rd Gen Colt SAA case color work was done by Case Color Co in Ohio (Don Menk,,ret'rd now).
Some 2nd gen by Dan Cullity in MA I believe also.
I don't know about the F series.
Two or three years after the F series guns were done, Colt really went into a tailspin,,a 5 year long labor strike w/ unskilled workers were brought in make up the labor force
All 2nd gen I have seen are excellent quality.
FWIW,,US Firearms Mfg Co in HArtford planned on putting out a series of 'Colt' percussion revolvers at one time. This was after their SAA's gained wide acceptance. The company was still using parts from Uberti at the time and reworking them to build their SAA. The percussion revolvers were made up the same way.
The project got no further than a handfull of completed and finished pistols for display and checking possible markets.
Some others were completed and finished up 'in the white' and left that way contemplating orders I can only guess,,which never came.
Those in the white pistols included some matched sets, one of which I bought from a local shop who was a USFA dealer. He must have been offered them on a close out of some sort.
I have heard of others being around too.
On one of the pistols in the set I had (1851 Navy's) you could just barely see a portion of the orig Uberti bbl address.
Beautiful polishing job as usual from them. They made a nice engraving project at the time.
I wish I had a pic or two!
