High Standard of Hamden, Connecticut also manufactured a small number of T48 rifles, I saw serial number HS 13 which was a lightweight example designed to reduced the total weight, the other High Standard T48's were the standard model. I could never determine the magazine used by High Standard but believe it might have been the FN.
H&R also manufactured 500 T48 rifles all with the standard weight barrel and with HRA marked magazines.
Winchester also had an example of a double barreled T48 chambered for the necked down 22/7,62x51mm cartridge too
