Great little pocket guns!
I have a Colt JUNIOR and used to have a CZ Duo, both .25 cal. Not much stopping power, but better than a limp dick.
The CZ Duo was a WWII soldier bring back and was in the original flap top leather holster. It was as new. I showed it to a couple of gunsmiths who specialized in military weapons and both agreed it appeared to never been fired. One made me an offer I couldn't refuse. My reasoning for letting it go was since it hadn't been fired (made in 1943), I wasn't going to shoot it and I didn't have use for a weapon I wasn't going to shoot.
I often carry my Colt in my tackle box.
