Just picked this up in trade and was wondering when it was made? It is a beautiful gun in as close to new as possible without being new! looks like a 6" barrel with the 3 Ts
8K29576 serial number
Thanks
Bill
I have a Model 17-3 that I bought new in 1975. It shipped that year and is just a few thousand numbers higher than yours.
1975 would be a heckuva good guess!
