I thought I ought to explain a bit as to what went into this project.
It is essentially an early 39 slide on a 639 frame. This entailed eliminating the firing pin safety lever and fashioning a noninterfering spacer as a substitute for it. A 39 sear release lever then had to be thinned down so that it could be installed beside the spacer and function as it should. The photos are not quite as good as I would like, in that they make the frame appear as if it has been bead blasted, but in fact it still bears its original brushed and somewhat shiny finish on the sides.
The rear sight is from MMC. The barrel is teflon coated. The backstrap is a steel one for a Model 52, but I removed the protruding tab at its base. The hammer is from a compact version, but as I said in a previous post, I don't recall precisely which one. I opted for a full barrel bushing. I'm thinking I might install a blued recoil spring guide (again, I've waffled on that).
This pistol has worn various stocks along the way, the oversized, finger groove design pictured being just the most recent, although they feel really good and probably aren't coming off anytime soon.
I've included a few more close up views of this pistol illustrating some of these details.
