Update !

I've just checked my other spare parts machine that's an identical unit to the one in the photograph apart from its poorer condition and that one has two lots of witness marks just below the halfway mark down the handle but those are consistent with the optional toolbox being fitted and as such there are no other tell tale signs whatsoever of any metallic parts fitted around the tube. It still has the original Villiers throttle control and cable fitted.

Cheers,
