I still very much doubt the max total of 110 produced for the Vulcan SE.
You see them far too often for that. They were listed for sale from 1980 upto 1984. Thats way too long for 110 pieces.
It might be that the late Series 1 SE's were limited to 110 but I dont think the Series 2 were limited to 110.
Pitty its nowhere to trace exactly, as the webley bible isnt very clear about it either, the 110 sentence only speaks of the Series 1
