Continental A 40 engine tested on the Junior

Maintenance record entry shows in 1933,  N10907 was issued an “Experimental or Restricted license to determine the feasibility of Continental A 40 engine in this type aircraft, to replace Szekely engine which is no longer manufactured. ”   This work was done by Airtech School of Aviation in San Diego California.

Records do not show the outcome of  the testing, except  that the Szekely was reinstalled.
