Thank you for the useful link Dave.
There are two features about this lock that make it interesting. The first is that it appears as though it’s the eye that removes rather than the shackle. More commonly it’s the shackle that removes. The other interesting feature is the small protrusion on the end that removes, presumably to assist in withdrawing the bolt once the key has compressed the barbs.
I’m sure that the artisan that produced this lock ‘borrowed’ the design in much the same way that its possible even today to buy locks from the middle and far east that are made in both the style and technique of many generations before.
In all that’s a very interesting find.
