Gay, its only got one gear! 
yeah am on the hunt for a frame mounted shifter then it'll have 7 again! 
Do you want one that clamps round the frame, or bolts directly to it, and what make? I may have one 
Thom
not fussed if it does the job boss 
I've got an old Sachs Huret one that clamps round the frame, twin levers for a 10 speed, but one side has a broken lever, this can be removed by undoing the nut
PM me your address, and I'll stick it in the post
