Copper cantle hunting sporrans?

[McCracken140]

The OP asked about copper or bronze cantled rather than brass. Both are much rarer and neither widely available as far as I know. By way of comparison, here is a brass cantle and a bronze cantle side by side, the latter is mid-18th century.

Yes, the idea is to get something that matches my watch, so I would prefer to get a leather cantle rather than a brass one that didn’t match.
