Round Metal Object

[RiverRat3]

Found this about a month back. Been so busy with work that I have not been able to hunt or post this item on the forum. This was from one of my CW sites that has turned up a lot of trash. Quarter is for size reference. Object is a little heavy for size. I think the back is lead.

Bridle rosette or maybe cartridge box plate I'd guess. Nice find (even without being certain of which, if either, it is). I can see horizontal lines and part of either a letter or figure of some sort, but I wouldn't rush to clean it further, yet. Someone more knowledgeable than me could make use of the diameter measurement (the quarter for size reference was good, but more precise can make all the difference. I'd say it looks like that sight is worth the hunting despite all the trash you mentioned!
Of course if a rosette it could be civilian, but I'm hoping for a military application.

Clean the back with water and a light brushing with a toothbrush. See if it is lead or solder filled, and see if there are any iron marks on the back where hooks were. (Don't wash these iron stains off.) If there are iron hook marks, then it is an unmarked cartridge box plate. My buddy dug one on a hunt with me in Kentucky back in 2008 from a site we got an eagle breastplate and sword belt plate plus keeper from.
