CAUTION...LETTER Req'd prior to BIG BUCKS VALUATION
I have S192649 and S203544, both of which are 4" Model 28's with no dash. Also, S192520 and S209632 are Model 27's with no dash. My only N Frame 357 "-1" gun is an 8.375" 27-1, SN S221453. That being said, it would be way cool if it was an original 28-1. Several years ago, I used to check every HP I came accross, just to make sure it was not marked 28-1. Furthermore, just for N-Frame reference, S187078, S200143, and S211004 are all Model 29's with no dash...
I too would love to see some photos.
Good luck,
