Hey Patrick L;
That's a nice, nice Trooper! You done good gettin' that one.
Do you know about when it was produced? A factory letter's best, but Colt offers an online lookup feature that will yield the year.

I love traditional Smith & Wessons best, but am doubly afflicted and also love old Colts.
This early "first year" 3 5 7 from 1953 has been roosting in the safe for some years now. In my view both the 3 5 7 and the Trooper are way ahead of the Python and its over the top styling.
