The only thing I have ever found on Ottawa were ads in NPN. The ads started 1n 1924 and ended in 1928.
They did sell other items: Air stand, barrel pumps, Oil Dispensers and air compressors. The compressor was probably made by someone else and just had their name on it. Same with the air post, the other things they probably made. I believe they were a small company probably selling most of their pumps in the Kansas area.
Your pump appears to be similar to the one they advertised in 1928. It states the pump was available hand operated, air operated or a combination of the two. It also states it was available 10 gal. or 15 gal. The ad also the address of the company was in Ottawa and Pittsburgh, PA.
BTW, do you have a model number for this pump?
