I would be happy to update the sections of model 41, 41-1 and 46 if you would like. Just as I did the 4th ed.

I'm happy to also submit other articles also which are missing from the 4th or very briefly mentioned.
Like;
S&W (Wesson) double barrel shotguns. ~1860s.
DB Wesson single shot rifles. ~1849
Rollin' white cartridge pistols. ~ 1860s
Of which I have examples of all and could also provide photos.

There is probably others I need to check my notes. Like the 50 or so model 14s in .32 come to mind....again I have examples
