So, your question has been answered - that's always nice! It's even better that the camera already has a tripod mount. I was thinking along the lines of the Charten cameras, one of which I have. That camera has a similar hole on the bottom, fitted with a circular aluminium (?) ring that the tripod attaches to. Your camera looks pretty nice, and also came with a mounting flange attached to the lens board. If you measure the diameter of the thread, I am sure someone here will be able to tell you what shutter/lens will mount to it.
Good luck, and welcome to the forum!
Best wishes,
Sanjay
