I picked this up from a retired machinist in a lot and at first glance I thought it was a toolmakers vise but couldn't find any info on it or the company. Hoping somebody could help with identification on it's purpose as it is different from anything I have seen before. It has interchangeable fittings so may be a small press of some sort. It's very small at 4 1/2" x 3" so was leaning against the press. It has a patent number of 141995 but I couldn't find a patent with that number. Any insight would be greatly appreciated.
