As an aside, we cannot lay all mistakes (or omissions) in letters at the doorstep of the Historical Foundation folks. All they have to work from are the factory records.
I had an 8" .32 caliber Single Shot. It lettered as a 10" .22. That "mistake" came right out of the factory records. Roy sent a copy of the shipping records to me---and there it was, big as life, #14272 shipped as a 10" .22. Given a vivid imagination, I figured the nice little old lady who wraps the guns, and sticks them in a box, grabbed the wrong box----and nobody at S&W looked in the box after that----never mind I have never seen a box for a 1st Model Single Shot, and have no idea if it notes the caliber and barrel length or not.
Chapter Next: I had a New Model #3 Target---one of those chambered ONLY in 32-44 or 38-44 S&W. This one (#3914) was chambered for "38 WINCHESTER CTG"---as stamped right on the barrel. The factory records make no mention of the caliber---only that the gun appeared to be a special order for a single unit. Given a moment to think about something like that, you'll come to the realization the only two folks who needed to know what the caliber was are the fellow who made the holes in the cylinder and the barrel---and the one who stamped the caliber on the barrel. Now the only other thing anybody else needed to know was that they got paid for the gun, but that's about the end of it.
All that said, if/when the Foundation folks make a mistake, they'll fix it first thing---right after they find out about it. And if they can't "fix it", they'll explain it. That'll come as small comfort, 'cause the folks who made the real mistake (or omission) are long gone!
