Jim at the SWHF came up with some documents!
I cannot stress enough how important it is to join and contribute to the work they are doing. Over the coming years the information that comes out of the work they are doing is going to provide a huge draw to new generations of S&W collectors.
Here's a couple more photos of it. I need to get some better ones, I have no idea why but I can never seem to have a good time to photograph this gun.
So that letter is interesting in that it does say that the gun is as it came from the factory. Which...I don't think is as modified.
I suspect that whoever C.D.H. is did the short action conversion in '49. But I suppose if there is some missing correspondence here referring to the short action modification...which could certainly have resulted in light strikes, maybe the conversion was done right away on the gun?
Opinions are more then welcome on this.
