Yet another part id query :-)

At Ferrymead Aeronautical Society we’ve had a puzzle part surface which hopefully someone here can ID as it is an Air Min item and the data plate says 10K/120066 but the last digit is damaged so it could be a 5 or 8.

It is called out as a Motor Generator taking 11-2V 3.8A and outputting 480V and 0.04A, the manufacturer is English Electric.

Naturally we’re interested in its use so as to resolve how it comes to be here in NZ.
