Yeah, the giant clothespin on the right is generically a vise, and with padded jaws and operated by a foot pedal, for something quite light duty, like stitching.
The other thing... My first impression was that it was an unusually aggressive boot scraper. But it was clearly meant for a shaft to lay in those half-bores (and there may be a missing top portion to whatever it is). What it was used for, what the curved spikes guide/sort/shave, I have no idea.
