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.
