Well, not to sound like I'm bragging, but I ended up with a complete set---sort of---didn't have a transitional---never even saw one to be had. That aside, I was a certified single shot nut, and when I got close to having one of each, it became a life's mission---and I'd almost made it---all except for an 8" 3rd Model. I'd never even seen an 8" 3rd, and figured my chances of getting one were slim to none---and Slim left town last week!! (There are 3-4 8" 3rds on the Club Gun List, and I'd about decided that's all there were anywhere!!----not so!!)
Then, out of a clear blue sky, this forum member, an avid big game hunter who lived in Arizona, and who every year made the trek northward to where those GREAT BIG deer critters called Elk and Moose are to be had, stopped at a little gun shop in Utah----and because there's a God in heaven, there was an 8" 3rd Model---a very spiffy one---and he snapped it up---and called me when he got back home.
Here's what an honest to God complete set of single shots looks like-----without a transitional: 6/8/10" 1st Models--6/8/10" 2nd Models--6/8/10" 3rd Models--an early and late Olympic Model--an early and late Straight Line.
Getting that early Olympic Model was another favor from above. I used to carry around a .22 Long Rifle cartridge to try in any 10" 3rd Model I came across---in search of Olympic models----and I didn't even know there were early versions. So here's a 3rd Model, and I try the cartridge, and it sticks out too far!!! My knee-jerk (and totally off the wall) reaction was it was chambered for a .22 Short---never mind it didn't stick out anywhere near THAT far!------and never mind it said .22 Long Rifle on the barrel!! I called Jinks to see if they ever made a 3rd Model in .22 Short. He gave me his stock, standard response to dumb questions like that---"They would do anything anybody would pay them to do." I went home without that gun.
I went back to the same show (Louisville) the next time around, and that pistol was there again---still! I figured the good Lord was looking out for me, and bought the gun. I called Jinks again, and asked a better question this time----and got a better answer. There are two different versions of the Olympic models---early and late. The early ones had an even shorter chamber, and were the topic of a significant number of complaints about the difficulty to seat the round. So S&W lengthened the chambers----by a whole .025" (+/-). (This happened somewhere between #'s 10617 and 11112 (my early and late examples), and that was as close as I ever got.) As an aside, I tested both guns for accuracy, and they produced identical results---which perhaps needless to say, were VASTLY superior to the standard 10" version.
And that's the tale of a complete set of single shots from a total lunatic fringe collector who kept on keeping on---no matter what!!
