Kellogg-american 201 history

[Clayton94]

Hello guys new to the site as I picked up a old Kellogg-american 201 for free. I'm trying to restore as best I can and would like to know more about it. The tank it's attached to is from 78 but no indication on the pump, some older threads indicate that the it would be on the model plate but nothing, simply model and serial number. But when I pulled it apart I noticed it said K37 under the valve gasket, and I was thinking that it was made in November of 37, the only reason I think of this is cause in the military we use letter/number combos for ammunition to tell when it was made.

Any help would be grateful especially since I'm trying to do a full restore. Thanks in advance

1937 seems to old, but I'm not an expert. Can you post a pic of the whole pump?

So I recently put it all back together and can't build past 40psi I fell a slight blowback from the intake side but also think theirs is a exhaust side leak. I was wondering what I need to do to fix it or what parts to get

Did you do anything with the valves while it was apart? Good chance it needs the valves serviced. Thread where I did mine here https://www.garagejournal.com/forum/showthread.php?t=333731
