Well, I'm now one step closer to my quest of "One of Each Caliber, Unconverted Old Model Blackhawks". Hard to believe I found my most recent addition. I should say, my son found it. Got a call from my son about an unconverted OM Flattop .44 he saw.. I said, are you sure its a Flattop, not a Super Blackhawk? Yes. Have them hold it for me. He called back, its got your name on it. Sure enough, it was an unconverted .44 Flattop Blackhawk. Its just a shooter, with holster wear and a turn line, but, good enough for me. So very happy. One caliber left to go. And a couple of barrel lengths
