Research status

Maker and intended 51 mm width are confirmed. The meaning of the D.R. mark with its pictorial device is unresolved. An original factory pairing of this plane with the 51 mm JACK iron is not claimed: only that the iron comes from the same old workshop as the owner's 600 mm JACK plane (which carries a 61 mm iron).
