Is this a common tag in these?!

My 57mm does not have one. And the 6lb, and 2lb is British nomenclature. US never called pieces by weight.

One thing strange, the 6lb and 2lb, used different shields.

The late 2 pr uses the carriage and shields of the 6 pr.

Makes you wonder how this gun ended up with a British shield.....Image

Thinking it was possibly battle damaged or was lend lease return

Mine was a 42 Yoder gun, it was a basic M1 early type, and a copy of the 6pdr. If you look at the shell bases they are listed as both 57mm and 6Pdr. we got ahold of their blueprints and made anything we could to get weapons ready for WWII, in later 42 or so we redesigned weapons like the 57mm to improve the carriage and for some stragne reason add a recoil attachment above the breech on the later 57mm guns even though there was no recoil group up there (must have had plans for alternate gun tube use)
So there's a full chance the tags were on the guns, but have been removed during service or rebuilds.

Odditiies I noted:
-The right hand shield would not take a NEW NDDC tire on combat rim without rubbing (I towed it home during recovery for 100 miles rubbing my Command Car tire edge)
-The darn lunnette is too small to fit behind a truck (hence the extended version of the M1A1 carriage) I have no idea how the early guns were hooked into the 3/4T or 1-1/2T Dodges, the spade trails hit the bumperettes when trying to connect the basic M1 lunnette to the stock 3/4T rear end so it would not hook.
-Breech threads are Left Hand (after heating and trying for an hour I pried the opposite way and she came apart easily...)
-Collector friend in Ga has a nice M1A1 gun and even a set of the rare axle clipped side shields, which must have been real fun to liftup and place on each side of the halftrack before moving out, as they must weigh 150-200Lbs each

From my understanding the recoil lug above the breech is for when it was mounted in a tank.

A couple more strange things...

The 4 holes in the left shield, I have not ever seen a Photo, manual or old WW2 video showing anything mounted there. There was a doc on North Africa last couple days, and it shows them firing a 57mm, I paused the TV and looked at several frames, nothing is mounted. The Story of GI Joe, has a really good section in it of a Dodge coming through a arch, stopping, dropping the 57mm and firing it, at a pill box in about 30 seconds. It does not show anything on it.

After we went to the free transverse, Why did we leave the cutout for using the have wheel? It takes extra steps to make it, extra steel, and extra time when it is not needed.

I can understand making the hoop for a tank recoil, but we'd need a tank that needed the gun before we needed to modify the breech (M1A1) and I cannot recall any post 42 tank that had the 57mm, only 37 then 75/76/90, etc.
And yep, making a dome to cover a hole for a traverse mech was a strange "stick to the blueprints" call, I read in wikipedia that the free traverse was a mod made by the Brits, so were were really just plowing ahead in manufacturing, not looking at results in the field.

The first tank to go into action armed with the 6 pounder gun, was the Mark III version of the Churchill tank, in the Dieppe Raid of August 1942. They were deployed to North Africa; six, as 'KingForce', were in action at El Alamein in October (destroying five tanks and three AT guns for the loss of one Churchill).

Guns of this type were mounted on several British tanks and armored cars, including the Churchill tank, and the U.S. mounted it in the M3 half track. The Royal Navy mounted it in gunboats, which also had a quick loading mechanism, enabling the gun to fire 6 rounds in as many seconds.
