Well, I was able to get the Single-Six this afternoon and I am impressed. It has the 6.5" barrel, fixed sights and the finish is at least 98%, maybe better. No rust spots or nicks, just a very little wear at the muzzle and the leading edge of the plunger housing. It was made in 1963 but couldn't have been shot much. It never had the transfer bar feature installed. The seller inherited it from his father. He said it had been stored for at least 20 years and I believe it. The bore is pristine. I can't tell if the magnum cylinder was ever used. It has the slightly larger grip that started that year (I prefer the smaller, original style used on the 50th Anniversary .357 Blackhawk) but the wood is well-fitted and nicely figured.
Several features caught my attention. The rear of the front sight is lightly serrated to cut down on glare. The rear sight has a square, not U-shaped, notch which gives a very sharp, clear sight picture. This gun is TIGHT. There is almost no noticeable movement of the cylinder whether the hammer is down or at full cock. The trigger is a joy. It isn't a hair trigger but there is no take up. It breaks very cleanly. This is the closest I've come to the traditional "breaking the glass rod" feel I've heard about. The only thing close is with the double-set triggers on my muzzleloaders.
I had a chance to handle a couple of new manufacture single-sixes this week and there is a slight difference in balance from this Old Model, 3 screw version. I prefer the feel of the older model. It feels a little steadier in my hand. Whether this will translate into better shooting, I don't know. I hope to get to the range this weekend to try it out.
One thing: this gun will NEVER get the safety conversion installed. It is too smooth and precise to risk messing with it. If I ever carry it loaded (unlikely) I know how to safely load five rounds and put the hammer down on an empty chamber.
If I can figure out how to use the digital camera (I still prefer film) I'll post a picture.
I had toyed with the idea of getting one of those limited run Blackhawks in 44 special that came out a few months ago. Having felt the older style Rugers with this Single-Six and the 50th Anniv. Blackhawk, I would prefer to look for a 44 mag. flattop Blackhawk and just shoot 44 specials out of it. Can't do it any time soon, gotta save up, but something to keep an eye open for.
Thanks again for the advice and encouragement.
