Hi Brian,
According to the Brough family organisation of the USA who contacted me a couple of years ago I am George Brough's sixth cousin 4 times removed.
The Car in my avatar is a 1935 8 cylinder Brough Superior Drophead Coupe and i am lucky enough to be the owner.
Is the bike you you are talking about one of the Austin 7 engined ones, or an SS100. Always wanted a bike, one of my biggest regrets in life was when I was given details of a very nice SS80 14 years ago that was for sale at around £13,000 and I could not pursue it as I didn't have the money.
Mind you I was talking to someone at the new Brough bike launch a few months ago who bought his up and running SS100 in the mid 80's for £3000, and I know someone who got his car in the 70's admittedly needing restoration for cutting the grass. How times change.
The side cars were interesting in that the chassis tubes on them formed an auxiliary petrol tank. You maybe interested in this book if you don't already know about it, The picture of the bike and sidecar on the cover, shows the petrol tank tube going up and over the front of the sidecar, my car is the blue one also on the cover.
