Reference is made herein to a German patent dated 2 February 1912.

There is a very good chance that the "Patentirt im Deutschen Reiche vom" on the original on said patent says 3 February 1912, as per our observations on patent dates. There also may be some interplay between the multiple corporate incarnations of Edmund Rumpler along with his filings as an individual.

This is essentially the same as Patent GB-1913-513.

It has specifically to do with corrugation of the reinforcement structure within airplane wings.
