T's had shorter barrels than E's, or F's, so maybe they thought that justified them calling them featherweights?
Also don't discount the value of the term "featherweight" when you are trying to market a gun.
But I agree in principle with you Rory, the E's and F's are more of a "featherweight" than the T's were.
The "G" - now there's a featherweight
