Regarding national tech category, there are peculiarities here, with DE 77h.5, that is, its German and archival equivalent being scratched out, on the original, and with "62b 45/03" being written in. That is, it could be read as "KLASSE 77h, GRUPPE 5 62b, 15/03".
This has primarily to do with a planar hinge, the shape thereof, in the rudder.
In keeping with our observations on patent dates, we are taking the „Patentiert im Deutschen Reiche vom 13. März 1917 ab.“ shown on this original document as one day after this patent's filing date in Germany.
