Mack,
Nice pistols, but you know that technically the Remington '58 New Army models you have weren't produced until 1863 don't you? The '58 refers to the Beal's patent. If you want to be even more accurate use your U.S. Model 1848s for your .44 caliber pistols.
But I guess if Sherman can pretend he has a football team we can ignore the Remington actual production dates.

I've about had it with the coordinators...
So call the Pistols early Beals models, .31 calibers from '57 to '60, .44 caliber beginning in '60 as the Beals Remington (no safety notches), followed by the Old Army in '62 and the New Model Army in '63.
I really like those ivory grips, they really give them a special look...
I'm yanking your chain though, since the period runs from 1840 to 1865 the New Models fit right in.
Regards,
Mako
