Bruce, had a look at the manual and looked at all the spots that it showed a model no and couldn't see any model numbers in those spots. It just has the patent number in the top of the housing being:
4.480.501
4.103.566
RE32.125
Not sure if it helps?
5 speed peerless transaxle.
Top centre input, external brake on rhs and gear selector on top left.
Would pictures help?
Any other way to identify it?

Thanks.
