The above military engines are basically similar to wright GR-2600 series type certificated engines.
When the above military engines are incorporated in certificated aircraft, the engine nameplate should be
stamped "FAA Spec. No.  If there is no room for this information on the  existing nameplate, such
information may be stamped on a plain thin metal plate attached beneath the existing plate by at least
two of the mounting screws.
Before these military engines are eligible for use in certificated aircraft, engines with a 3-point
priming system should be I  and elbow which
incorporates a synchronizer valve  Model p-2600-20 incorporates a tongue meter and narrow vaned supercharger impeller. The R-2600-294  the supercharger clutch.
NOTE 6.  The following spark plugs are approved for use on these engine models:
AC  181, IS-88
EG  RB27R- 1
Champion
NOTE 1. Alternate gear boxes, Wright P/N 417916 or 424010 are eligible for use on the R-2600-35 engine.
