Bit of a long shot, but I intend to build my Albatros as a later model (probably Allmenröder or Schäfer), although I have the wing with offset radiator sorted out, these were later aircraft with the square boarding step.
Allmenröder's even had 2, like those on OAW built D.IIIs.
Anything is scratchbuildable, but perhaps someone thought the Roden detail good enough and did not use these parts?
Partial frets are also welcome., as long has they at least have those 2 parts on them

Willing to pay or trade for something I might have.
