Can't hardly resist posting a few pictures in this category (smile). Next to N-framed S&Ws I love Flat-top, 3-screw Rugers for Single Actions and have been lucky enough to acquire a few. My favorites are the Blackhawk 44s.
This is a fairly rare 7-1/2". If my information is correct there were only 750 made in this barrel length.
Next is my 4 digit 6-1/2". It has the thin, curved trigger and non-collard base pin of the earlier models and the plastic stocks.
The last one is a semi-custom 44 Blackhawk that I (and others) think Ruger should have offered. I bought one that had been mistreated and abused and made it into the gun Ruger should have added to their Flat-tops back in the late '50s and through the 1960s.
I have two Flat-top 357s but the board won't let me post 5 pictures and I couldn't decide which one to leave out (LOL).
