Good day all

Picked these up from ebay, only 1 key which operates them all 7 lever, one retains the key when open.
Any insights would be appreciated.

No modern blanks available. Have to fabricate blanks to do it right, the pins are tapered ..

I have a lock from the same system. Quite sure these are ex museum show case locks and were made by Chubb to match existing Hobbs keys as the design is a Hobbs one not Chubb.
