Found a guy on Ebay with the same pump for sale. He says it’s a Gilbert and Barker, which is where I was leaning but it is far too short in the base. I sent him an inquiry as to how he came to the decision that is what it is.

If in fact it is a G&B does anybody know of a more scarce model? Best I can tell it is a full 7” shorter than a 176. It has not been cut.
