This interesting little item was obtained from a source in Oberndorf am Neckar, and according to shape and size it offers an interesting view on the production of Mauser M1910, WTP and WTP2 magazines.
The tube is roughly 12.7 cm (4.72") long and it's diameter and shape is consistent with that of Mauser's M1910 pistols except for the early M1910 sidelatch, which uses a slightly narrower magazine tube), the WTP and WTP2 pistols in 6,35mm / .25 ACP.
The round cut at the base of the tube corresponds with the overall shape of the top of a .25 ACP magazine which suggests that the actual tubes were drawn even longer and that multiple magazine tubes could be made out of a single tube.
The tube snugly fits the magazine wells of all 3 pistols mentioned, with the exception of the M1910 sidelatch. The tube itself is drawn and shows no signs of welding or brazing.
