After 30 plus years your car original "FS" key must be pretty worn out. Triple-C has the largest selection of New Old Stock Wilmot Breeden "Union" keys available anywhere. This listing is for a single NOS "Square Head" (Polybow) style FS key manufactured by Wilmot Breeden prior to 1987 when the company was sold and spit up. One side of your "square head" key has the all important Made in England Union and the reverse has Wilmot Breeden and the biting information. This listing will get you the key in the biting of your choice in POLYBOW (Square head) shape not round or rectangular - we have a very limited stock of round and rectangular original keys and you need to phone or email us if you are looking for one of these. Please note these are 100% genuine old stock keys, some are a little dirty some have a little grease on them but all are unused 30+ year old stock.
