I came across this machine badge recently for Craven Partitours. The Partitours were organised by Ken Craven and his wife Mollie, of pannier and rack manufacturing fame. Riding into Europe from the UK in the immediate post-war years was considered quite adventurous, Ken and Mollie as seasoned two-wheel tourers would lead groups of fellow enthusiasts across the Channel for a taste of riding on the 'wrong' side of the road.
Craven Equipment is still going, under the wing of Draganfly Motorcycles.
The Mojacar Motorcycle Touring Club founded by Ken and Mollie is also still going strong.
The Velobanjogent has a great article on Craven panniers with a little about the tours.
