Is Jena misspelled?

That will hopefully work. It's from 1931. Considering the size of the board I guess it might have come out of a Graflex. I saw a 3x4 press camera a few months ago with the same lens. There is various info on the shorter [135mm] and some longer versions on google.

This one gives the coverage for the 180mm version. I'm guessing you could just do the math to figure out the coverage angle and compute the coverage for the 165mm.
