[norfolk regt man]

Hi all, currently on eBay is a 1st city of Norwich volunteers badge, which is , in my opinion 100 per cent right. It has a tiny bit of damage on the strap end and is non voided.
But on the back is a two pined plate, of which one pin is missing and been replaced with solder. I can only think this has been done to mount it onto something other than a shako, maybe a display, maybe a shield/ trophy, or ………..
Any one got any other ideas.
I am unknown to the seller, and I already have an example of this badge, and will not be bidding on it. Thanks Andrew
