This cylinder (used) is fitted with an original Lockwood 'RDF' Restricted profile keyway.

The RDF profile dates to the 1960s-1970s. The two original Lockwood RDF keys are New Old Stock. As per the photos, the bitting on the keys is sharp. Quite rare for original Lockwood keys that are over 40 years old.

Lock and keys work as they should.

Would make a great addition to a lock collection.

Thanks for looking.
