The bore seems a bit large for 7mm, maybe 7.5. Pinfires were made in both calibers as well as 8mm, 9mm, 10mm, 11mm, 12mm and perhaps others.
FWIW, I know of no source of pinfire ammo of any caliber except the odd round at gun shows. AFAIK, it is no longer made anywhere, not even in Europe. Any ammunition you might find would be around 100+ years old and would not be guaranteed to fire.
I think that with a great deal of patience and a lot of work, a few rounds might be hand made, but I can't see anyone doing so for less than a small fortune.
It does seem strange that an entire ignition system, very widespread, and used by the military of several major nations, should have disappeared so quickly and so completely. But that is the way it is.
