I am brand new user of this site and older than most.
In my younger days a friend bought an AJS 10R racing bike.
This was in Normandy near Guildford.
It had rigid rear, girder forks, looks just like 7R but was 500cc
and had Amal remote needle carb and 5 gallon aluminium fuel
tank. I had many old bikes which I would love to have today
including 250 JAP OK Supreme but would give left testicle to have that AJ.
A google search reveals no matches for this bike, do any of
my peers have any info?
All best to all
