OK, sorry if I am going over old ground.
But my '55 4 speed FG-hubbed Raleigh roadster came with a steering/fork lock, but - you guessed it - no key
Now I have read before that there are two kinds, and if you have the lock number a new key is easily obtained. Certainly there is a guy on UK ebay who will do them.
My problem is I cannot see a lock number, only a patent number
Any clues as to 'where-to' from here?
