This brass anchor medallion is naval symbol that
would look great on a Navy model Colt (either the single
action type or the more modern 1911 pistol). But that
doesn't keep it from being used on any other gun grips
that you wish to have made!
The diameter is about 0.6 inches, slightly less than 5/8 inch.
It fits well with most gun grips. The images show a medallion which has been buffed to a bright shine, but
they actually have an antiqued, darker look when they
come to you. If you want them to be bright brass, just
buff them with a cloth buffing wheel having a little brass polish. Personally, I like the antique look with the dark background. You can also lightly buff the high points so that the anchor and edge molding is bright, and leave the fine lined background dark.
