I ran across this model 44mag with serial number 167521. The owner says it is made 1956-1957, 5 screw with 4 inch barrel,with 70 percent bluing. The cylinder has been replaced, Good action and bore, (according to the owner) The revolver is local so I could go see it. I am new to revolvers. My experience is with rifles and semi-auto pistols. I am ordering this coming week a 629PC but am curious about this old revolver. He is asking 500.00. I am hoping some of the members on this forum can shed some light.
