 I need the following barrel, any help would be appreciated. Rebuilding National Postal Meter. Nothing import stamped. Looking for MZ to be max 2.5 .

Underwood 6/43 - 8/43 , can be refinished, can have type III markings (none would be nice) NPM proof mark n- Large P if memory serves me correct.

Don’t limit yourself to this specific barrel. I have been looking for one in this range for almost 2 yrs now.   Also double check the proof you need. I’m newer to this but I’m pretty sure the large P is for Underwood. If you’re putting it on a NPM you will want a NPM proof mark which I know a lot were just a punch mark.   Your also looking at very hard to come by underwood barrel dates. NPM also used Marlin and IBM barrels.

Thanks for the reply. 
You are Correct. NPM used just a punch mark on the barrel. My 3rd block NPM has an Underwood barrel with both the P and Punch mark, original to the receiver.
The NPM carbine I am working on, the barrel  was ruined by the installation of solder on sight right over the chamber. 
Carbines can be a challenge at all levels.
