I bought this 939 6in H&R off a local site this am. It's an Ultra
Sidekick. According to the letter prefix it was made in 1966.
This one is from the first series, it has a key lock. The transfer bar came later. This is the best looking one I've ever came across. I drove up to Tulsa with the intention of passing on it if I couldn't get him to come down some more. I looked at the old
gun and dug out the money. As they say, this would be hard to
upgrade. HDHIC aha Cliff
