Can anyone tell me more about this machine, i.e. who made it and when?

There are no ID markings on it except a number 173008 on the base.

I think the tension is via spring action.

The pearl inlay are 3 roses in middle of metal base along with 3 leaves; there is also a scattering of shell pieces all around the edge of the rectangular metal base.

The top of the machine has 2 metal thread holders on the main body and 3 metal tension(?) bars on the top of the head; all are vertical.

There is a maze type gold pattern/trim outlining the metal bodies.

It has 2 holes in the wooden base where one could presumably bolt it onto a fixed spot, plus it also has a rectangular hidden (hollowed out) spot in the base (bottom right under wheel) to hold accessories.

The bent wood cover locks with a key.has a metal (brass?) carrying handle.
