It is a VERY pale yellow, so you may be correct. According to the caliper, it is .104~5 wide. I though it was stainless, a bit tarnished. The gun was not horribly dirty, but it was not completely clean, either. Still isn't. On the other hand, the finish is remarkably nice looking aside from the obvious muzzle wear, and a few nicks. Besides a couple worn Model of 1905 38's over the years, I have never owned a pre-WWII revolver. Or pre-1950. One other recent purchase and my Victory Model, and neither one of those have a polished blue finish like this. I don't know if this is how they are usually found, but this is an almost glass like deep blue finish (with muzzle wear and a few nicks). There is a strange story behind this gun, partly related in my other thread.
