This one seems to be a bit of an oddity. Serial number on the butt is V 42742. There might be an "R" in front of that. It has a blued finish (or at least what's left of one) and a 5 inch barrel. .38 special brass fits just fine.

The top strap is marked "UNITED STATES PROPERTY." It looks like there might be something next to it but it's pretty faint.

Serial on the barrel matches, and is marked ".38 SPL" on the right hand side. On the bottom of the barrel, it's marked "FCCSC(?) PENN N.J."

Cylinder arm is marked P 93191.

Cylinder is marked 948053.
From what I've read here, it seems unlikely that the blued finish is original, but it looks old as dirt. The grips definitely aren't original and don't have a serial number.

Can anyone give me more insight on to what I've got here? I'll attach some photos. Here's a link to the album if the photos don't attach correctly: Imgur: The most awesome images on the Internet
