Mortars? Anyone know?

Did the US reference them by inches or metric during WWII?

60mm and 81mm and 4.2" mortars during WWII. 60 and 81 mms were infantry battalion assets. 4.2 is commonly referred to as four deuce. 4.2 were used in "Chemical Mortar Battalions" as the 4.2 was created to shoot chemical rounds. 4.2 was considered artillery and was attached to other units like airborne divisions and ranger battalions.

Thanks All. Thanks Clem.

The US Army used metric measurements on all tube artillery and cannon but retained inches for small arms. The Navy used a mix, retaining inches for main guns (like on battleships), but adopted metric for secondary/anti-aircraft guns.

The army used a mix too.

We had 81MM and 4.2" mortars when I was in the service in the 60's-70's.

Not sure when they became 107mm, but they were Four-Deuce during Vietnam.

We also had 8" track howitzers.

Well, I never saw anything like that in the .81 mm mortar ordnance while I was in Uncle Sam's
club. Not saying it could not be something developed after 1960 when I left the active service.\I would not think a .22 blank would have enough umph to ignite the cheese to hoist one of these out of the tube.
Maybe a 12 gauge shell, but not a .22.

Besides, I do not see any compression rings on the sides of them. JMHO YMMV

I stand corrected. Size does matter. LOL

Make that a good cigar for Clem.

clem / Those are part of a sub-caliber training kit for the U.S. M29 81mm Mortar. They use .22 blanks as the propellant charge.
The long tube is the sub-caliber bore and fits in the 81mm barrel/tube.

They were a lot of fun to set up and practice with.

Kind of like a .22 conversion kit for a 1911, only for an 81 mike mike. Hmmm...
