Hello all, I ran across a 44 DA First Model in 44 Russian that appears to have the original finish that has faded to a brown color. There is no sign of a refinish or external corrosion, I would rate it at about 90% but don't know how the brown hue effects a rating. The gun is perfect mechanically but the bore is a bit rough. Lock-up is very tight. Rifling is present and appears quite strong. Both original hard rubber grips are cracked. I am having a bit of a hard time estimating the value of the gun and thought perhaps someone more experienced in these guns could help out. Thanks, John
