I found this stamp fragment in a cover I bought off
eBay a couple of years ago.

Since that time, I've tried to identify the stamp just for the fun of it. No luck so far after combing through the Scott catalogs a couple of times. So, I thought I'd let the rest of you join the fun.
The fragment shows some scroll work and part of a "5". Two perforations span 3.30mm making it gauge 12. It's brown.
Hope you have better luck than me.
