Old Revolver I D Help

[GNERGY]

My friend at work got this pistol from his Uncle that passed away recently and has no idea of it's manufacture and value. So any help would be appreciated.
Looks like some sort of pin fire. I can get more pictures if needed.
Thanks

Looks like a Lefaucheux pinfire. Not sure if that's the actual make but it's a very close resemblance.

Looks very close to this Belgian model

Try and find the proof mark

7 mm black powder. Handy if you have to dispatch a pesky rat.
