[Milsurplus] ID'ing a dynamotor (?)

[Barry Tuttleman]

group:

trying to ID what i believe is a dynamotor, and appears to be aircraft milsurplus.

unit measures about 6½" (L) x 2 5/8" (diamter), not including the mount.  the dataplate states "AUXILEC", and appears to be in french. one side of dataplate states "ALIMENTATION", "VOLTS: 22 - 29", "AMP: 7.5"; other side states "UTILISATION", "VOLTS: 115", "AMP 0.87"; also states 400hz.

other items in the same load appear to be french (?) surplus; many have the "S.T.T.A" logo (?).

any info appreciated; items will be for sale.

tnx,
