It looks a lot like a Fellini. Collectible
Do you have pictures of the top, bottom and inside?
Looks like a Kelli.
9" in circumference and the rounded over ends give it away, definitely Kelli. If you still have it, compare your Schon lock rivets to the ones in the photo.
I don't have a Schon case yet.
I have a Kelli. NOS I the original plastic sleeve.
AFAIK some rivets vary. Makers changed rivets according to the thickness of the leather apparently.
I understand. The latch kit came with those rivets. But if the material was too thick the maker needed different rivets.
Rivet head sizes vary. There is no standard.
.
Case makers bought the locks and rivets separately, and the locks never varied because they were manufactured by only one company.
Rivets, on the other hand, could be sourced from different makers. Again, the length of the rivet that fits the lock does not change the head size or diameter.
The rivets used tell a story that many overlook.
