Chatwood - Kromer wallsafe/locker lock?

[chubbbramah]

This is a wallsafe/locker lock faintly marked ‘MADE IN SWITZERLAND’, with one original key stamped CHATWOOD, presumably bought in from Kromer. The lock provides for 3-point locking at top and bottom of the door, but this was not used — the original case plugs are still in place.
The lock was collected from the Manchester area in the 1970s by a now-dead collector, from a disused bank building.

Apology for duplicate pic, there should be some more here, but will have to post another day.

That Chatwood number relates to November 1879, but I don’t think Kroma made keys that said “Chatwood”
Chatwood cut off the bow and silver soldered on their own.
1879 is 6 years before Chatwood bought their first batch of Kroma 12 lever locks and also probably 6 years before Chatwood produced their first double bitted key lock.
