Just picked up this .44 flattop and noticed the rear sight is not marked with the MICRO stamping. Second serial number falls in the 7 1/2" barrel length but this one is clearly a 6 1/2". Also steel ejector rod housing 'strait' with collared cylinder pin. Upon looking further and sending pics of the rear sight it was noticed that the area the rear blade fits instead of being square front and rear the rear area is rounded. Two other collectors seem to think that this sight is a prototype sight orinally for the super blackhawk. I think a factory letter is due on this one.
