A Brief History of the Marque

Established 1912 in Birmingham, the Watsonian company restructured in 1989 to become Watsonian Squire. In 1955 there were around 160,000 sidecars on UK roads - half of these were Watsonians.

hello all

my Project is a Cambridge from Watsonian.
I`m looking for a break of this. May somebody can help me?

Peter Hoeffler / Wolfsburg / Germany


No. I dont means production details.
I means i need the complete break from Watsonian for my sidecar. The break is from grimeca. Production is stopped beginn of the 90th. It´s a disc-break. Was used for the Watsonian Cambridge, Oxford maybe Palma and other. I hope somebody know someone what have this break as rest from a crashed sidecar or from customizing.

best regards

Peter from Wolfsburg / Germany


Some research...
"My Guzzi Watsonian Oxford outfit has a disc brake with the brake caliper hydraulically linked to the linked brakes of the bike..."
"I once had an old airhead BMW R80 with an independently operated drum brake on the Watsonian Palma sidecar, operated by a lever on the side of the chair by the left foot."

here some pictures

the first picture is from the Watsonian - Webside and Show the break. The next two is from my Project. And the last is the same type from a friend.

best regards Peter from Wolfsburg/Germany

i'm hoping you might be able to help me.my father passed away recently,and i inherited his sunbeam s7.as a child i remember travelling in this although no one in the family seems to know what happened to the original sidecar.after showing some pictures to some classic bike friends of mine,they quickly informed me this is the model i am searching for.i would like to find a near mint one if possible.so far i have drawn a blank.could you possibly help or point me in the right direction?also having never researched,have you any idea how much i would have to spend? the s7 is original and in excellent fettle,so i really would like a sidecar to match.
yours hopefully
