Im with Jaaack, the RT is an interesting topic, odd there is no factory info on this variant. I like them cuz they resemble the T”, and the forearm shape.
How about just the "T"? Their short barrels were not such a grand departure, carbines had already been widely accepted for their handiness. But the slender barrels with beaver-tail forearms? That was a whole new thing, maybe geared to the smaller-faster cartridge designs?
