At eBay, under number 7311017013, is a silver snuff box for sale,
hallmarked 1825, although the letter is not visible.

I asked the seller to let me listen to it, but he informed me (and
a colleague who asked the same question) that the box was already at
the shipper's!  I can't imagine why, so maybe it is a fake sale.

Kind regards,
