Rare Archive Info & Pics Of The Dixon Twin Cam 350 cc Douglas

Here are some archive info and pictures of the twin cam Douglas dad collected before doing his restoration , hope they are of interest to someone. I have also included some pics of the finished bike which dad sold in 2007 and was bought by the British Motorcycle Museum Birmingham .

Thanks for posting these - very interesting! I wonder when the top photo was taken: it shows the bike with footrests but no clutch cable (present on the restored bike) is visible. Now Freddie Dixon was a foot board man, and although it's a bit fuzzy one of the photos shows him on the bike perhaps fitted with foot boards. Did he use a foot clutch when he raced it in the TTs in 1928?

Hi Leon
I think your right about freddie using foot boards and a foot clutch as in the racing pic i can make out the boards and lack of clutch lever. I don't know were or when the articles or photo where published.
Dad also had a photo copy of an R.A Instruction / workshop manual but sold it along with the remainder of his O.H.V spares / bikes to a guy in Perth Australia.
The only other articles i can find are a couple of sales pics for the SW / DT models and an article on the Bayley / Cole douglas.

An article I wrote for the New ConRod magazine in 2007 about the Dixon two cam, primarily dealing with the engine. There is a link to a PDF version at the bottom of the post.
