I bow my head in shame, Chazzy B is quite correct. The Firefly engine was originally made by “Millers”, production was then taken over by Vincent.
I was getting confused with Vincents involvement with selling NSU Quicklys.
I shall now retire to a darkened room and dream of owning a BSA Dandy!
Thank you for your support...
