It is 2 stage / 4 cylinder; no obvious patent number visible, a hand stamped number ” A 16434 “.
It has barely legible casting numbers that kind of look like ” 433 – 158 “; and a casting logo that barely legible says “United Stated of America” … that’s it.
Who mfg. this pump?
Will appreciate your wisdom. Thank you.
