Dutch - I don’t know about the date the “@” sign came in. I also have
no way to know when the label was written. While as usual, I did not make
myself clear, I was referring to the firing of the case and the “T-3” series of
experimental 9 mm Pistols, originating in 1947 and last tested in the early
1950s, as I recall.
There were many barrels for the test pistols, as they experimented with various
ways to reduce what evidently was horrendous recoil for a 9 mm pistol, and also
with various rates of twists and bore diameters to accommodate the Army’s T-117-E
series of cartridges with various shapes and weights of sintered iron and plain steel.
These were first made by Remington I believe. I have a box from Remington for the
T-117-E-1 (Type A) supplied to the U.S. Army for testing. Stephen Fuller had one
of these pistols years ago, and it came with 17 (yes, 17!) extra barrels, each one of
To reduce recoil, High Standard finally copied a feature from a Mann 6.35 mm auto pistol,
and put various grooves in test-barrel chambers. I think we can see the evidence of that
cartridge case with the tag having been fired in such a barrel.
The tag could have been written much later than the firing of that case. Again, I don’t know, but at any rate, again, I was not referring to the date of the tag when I mentioned the 1940s.
