That double sure is interesting and even more the ammo. I don't know anything about it but if you have ammo for it, the ammo may be just as rare.
I did a search there are lots of double barrel pinfire pistols out there I didn't see any that looked exactly like yours though. I can't tell by just a picture but if it is old someone may have knocked off most of the finish and patina most of the other examples I found didn't look near as bright as yours.
