Looking for a used 16mm tang buckle

When I picked up my used Reverso Duo, it came on the OEM bracelet with no strap.

I've been very happy wearing it on the bracelet (my wife loves it too), but with the weather getting colder, I've been thinking about getting a leather strap for it.

There's a new OEM JLC tang buckle on ebay Germany as well one very worn (too much) example in Italy. Any advise on where I can find a lower cost used example in the US?

I posted a WTB (but no one looks there), and searching through the archives, I haven't seen one show up.
