Thanks very much guys

The difference is not that noticeable to anyone who is not a detail-a-holic like myself. It's just that the cylinder looks less 'royal blue.'

Looking the entire gun over with a jeweler's loupe (yes, I am a little 'off' I can see all kinds of 'imperfections' that are unseeable when handling the gun in normal fashion.

It's probably 97-98% overall and lookng at the cylinder in high magnification, it looks like the 'wear marks' from the bolt are obviously normal for a well-taken care gun of this vintage.

(And after fondling it, I thought against selling it too!)

Again, many thanks. I realize I contribute little to this forum yet I hope my gratitude for the wealth of information herein can make up a little for my lack of knowledge.

Stay safe, all.
