1946 Rohr MR-1, Guppe (or Guppy) NX90651

These photos of photos were taken from an album by Don Burnett. Don worked on the wings of the Lindbergh aircraft. Don also worked on this Rohr Guppe. One detail that I remember is about the wing rib construction. The ribs were aluminium with straight edges. The airfoil shape was formed by a shaped wood spacer. I obtained these photos before the San Diego Museum fire of Feb 22, 1978.

This aircraft was build by the Rohr Aircraft Corp of Chula Vista CA. Fred H Rohr was the person who designed and built the fuel tanks for Lindbergh's NYP Ryan.

Interestingly, I have never seen these photos published anywhere. If you have any information about this aircraft, please let me know.

Info from Walter Van Tilborg

...literature on the MR.1 I received from Bill Chana, the Rohr company and the San Diego Museum. Aerofiles is somewhat confusing on the Rohr designs. The M.O.1 tail first was some 75% complete, but never flew. M.O. came from Midnight Oiler because it looked somewhat like an oilcan. The M.R.1 (for McCreary-Rohr One) apparently made only a single flight. I feel sure that the engine was the 65hp Continental A65 as the Rohr documentation nowhere talks about the Aeronca E113.
