Copper half moons

[steelheadwill]

This is the 3rd example I have found, they range from 1.5-3"
possibly nautical, each has the incised line and countersunk holes.
thanks For Looking! & HH

I wonder if it is half of one of these??

thanks Creskol,
sure looks like that, I don't see evidence of breakage on this one,
looked through my 'inside' boxes for another, they are outside in 'Misc' piles.
will find others & check also.

I think they're part of cupboard latches. I'll look for a pic.
