That’s stunning!
I’d insist on handlers wearing cotton gloves if I had that in my collection!
Never seen any form of twisted key-bit like that before- amazing.
It’s really got me thinking- Overall it appears to have a bit of everything in there!
The key style and in particular the bow cries out pure Italian to me, but the intricately shaped drill-pin and pipe cry out pure French!
The style and finish of the lock case looks more typically German or Flemish, especially looking at the shape and use of the flat scrolls.
It’s got me thinking 🙁think):
Whatever it is, it’s a beauty that’s for sure!
