Bogie Cleans His Guns

I  will point out that I would get crucified for cleaning my guns in the living room and not putting down a lot of newspapers.  He’s also got four single-action revolvers that I can’t identify, a 1911, a 1903 pocket hammerless, a Luger, what looks like a M1917 S&W, a Model 60 S&W, a 1908 pocket hammerless, and some sort of small-framed revolver with a white grip.

I assume the grips are either bone or ivory, as Bogart would be familiar with Patton’s rule.
