Wanted: unused 300 series carkeys / locking barrels
 

I am trying to further complete my collection of carkeys and locking barrels of the 300 series.
I allready have a lot of them but my hope this to collect a complete set of all of the various keys and barrels so that I will be able to reproduce keys to help owners that have lost the key, need a second key, need a barrel.
So if you have any keys kicking around that are no longer in use or you have an odd locking barrell, or if you are scrapping a car, I am quite keenly interested.
I am willing to pay for them and postage (for the UK you can send to a local UK address even though I live in Belgium).
Many thanks!!
