Geof, Thanks for the link . Yes they look identical to the Morgan locks. Lots of the LR ones were similar but not identical.
Deejay, My problem is in the lock, as it does not work when tested on the bench. I've had a poke around inside and got it to sort of work, I would suspect that there is some dirt in there. I'll take it apart this afternoon, after Moto GP practice and qualy has finished.
Cheers
John
