Screw back, pin back and clutch back.....these are both clutch back and I am trying to ascertain which type would be period correct for 1945-46.

Clutchback DUIs such as those you have, are generally post-WWII. Not always, but most of the time.

 

The one on the left has a 3-character manufacturers code, D-22 in this case. That dates it to the 1960s or later because that’s when the 3-character codes were first used.

 

I can’t make out the market nags on the other one.

 

VERY broadly speaking, screwback DUIs are generally pre-war to early WWII. Pinbacks are pre-war to late 40s- early 50s, and clutchbacks are late 40s to the present.

 

As always, there are exceptions.
