You didn't mention barrel length of your M57...4"? 6"? I saw a set of unopened 4" tools the other day on eBay. I also just picked up an unopened set of 6" tools on the S&W Forum- I posted in "Wanted to Buy". You can also find 4-page manuals and other paperwork occasionally online or at gun shows. I had a 4" Model 57 that I bought new in the presentation box in 1978, and it was a great shooter. I reloaded and it was very economical. Unfortunately it was stolen a couple of years later and never recovered. For some reason, although I have many Model 27s, Model 28s, and Model 29s, I've never bought another Model 57. Great gun and great caliber...hmmm, maybe it's time to expand the collection! Good luck with the tools.
