If I owned that LNIB pre 53 jet, I would never shoot it, no way. Too many shooters out there to enjoy. Don't forget to keep the cylinders clean, I made my own tapered mop, out of a .38 special mop, it's not that hard to do, just a sharp pair of cuticle scissors, and you can get it fashioned close enough, I use alcohol,.
Also if you ever remove the cylinder from the frame be sure to buy that nice tool that clamps on the base of the ejector rod to loosen it.
Also Left Hand Threads. I will have to take a new group photo of the 13 on hand.
