Schebler Carb ID

[LouieMCman]

Looking for help identifying this carb, no numbers on top of body, has H55 on throttle lever, looks like 1" threaded connection, I have the 1928 Schebler service manual but not much help, thanks in advance.

That's not much to go on, Louie!

Can you measure the thread pitch, diameter, and direction (handedness)?
