Thanks agian guys,

Grumpey: that picture is tiny: but from what I can make out the numbers are not in either of those places on my engine. Indeed I can't see any numbers or names or marks anywhere on the engine at all...

Deejay: The electric machine only needs some type of coupler to attach the shaft of the electric motor to the drive shaft of the mower. There was a sleeve added to the electric mower shaft to make it thick enough for the clamp that is there but the sleeve failed. It keeps slipping. But I will leave that machine for the timne being and focus on my new fossil powered beast.

any one willing to give me an evaluation of the model 45? The styling and plastic parts look like an 80's model to me?
