Why does this reworked 90x600R case have a BROAD ARROW ?

[charley777]

Hello...
Can anyone shed light on this please?
USA had various AA, AT and AFV guns in this calibre.

It is a standard 90 x 600R case that has been reworked into the outer part of a sub-caliber device.
Missing is the internal barrel and breech for .22" rimfire .
This will have been for training (or possibly spotting ?).

WHY DOES IT HAVE A BROAD ARROW ?
Would the British have used these guns at any time?
In Korea? Or ?

According to wikipedia, (referencing this document, http://www.ibiblio.org/hyperwar/USA/ref/LL-Ship/LL-Ship-3A.html), the UK received twelve M26 Pershing tanks through the Lend Lease program, (six T26 and six T26E3 variants). These were armed with the 90mm M3 gun.

Hello,
More info on the complete device 90mm sub-caliber ?

 

[charley777]

Yes i would also appreciate more information.
The barrel inserts for sub-calibre use come in a variety of calibres.
.22 seems smaller than usual. They were sometimes .303 British (Commonwealth use).
USA used .30-40 Krag and i think .30-06 later. And so on.
