Lols....Didnt expect that...

Oh well, if thats the case, then Id have to say with what can be seen,and all the info provided that the best explanation is that its a Transitonal Model using up all the old GEB engines on the newer F61/2 bases. Very common practice for a lot of machines back then, including bikes and cars.

Id like to hear Jacks thoughts on this theory.

Either way I dont think it detracts one bit as both engine and base are period correct, and as Jack stated both engines ran side by side. In my opinion it appears to be original release regardless of its lack of model no and unlisted differences.

If it was an earlier gen 2 base with an LV engine Id be more inclined to think it was incorrect and had the GEB fitted at a later date...

Anyway its definately valuable historically as there just arent many Early Turners around. Just enjoy the resto and thanks for putting it up:)
