Hi everyone I've tried to put this in the classified but it wont let me, Sorry!
I've got a set of refurbed revolution wheels made in England circa 1970's I'm led to believe, pm me if anyone's interested.
I've just checked my bonnet and badge and I think your correct with your measurements, 1inch from front edge of bonnet to bottom of badge
and 6 1/2" from centre of bonnet to centre of badge.
Hope this helps
