Nice !
Thanks for the Show & Tell, I would not worry much about the difference between the tints, it is really hard to tell if some of the very early guns have been touched up at some time with cold bluing, many have, even though we like to think otherwise.
I have purchased some really dry guns that have been a very clear gray tint and have been surprised as they take on a different shade of blue gray after several weeks/months of being oiled regularly. Some sort of chemical reaction taking place I think when the rust bluing is protected from the air. This may be what youâ??re seeing and have nothing to do with a touch-up.
Thanks again for the pictures and comparison, I like your guns, wish they were mine.
