At the show today I saw a Model 58 with correct MM stocks stamped SAPD (San Antonio Police Department). Looked really clean and it was priced at $495. I had my wallet halfway out before I realized in was actually a Model 10-8.
Too bad it wasn't the other way around!
I found a real nice 631 that was marked as being a 63-1. This was at an auction and it sold for what a model 63 was going for at the time.
I was one happy camper.
