AZ 23 type fuze - nationality?

[Burney Davis]

I have attached pictures of a sectioned fuze which is almost identical to the AZ 23 German fuze of WW2 (which is on the left in the third picture). However, there are what appear to be Cyrillic letters and a date of 1941. Can anyone offer thoughts on nationality and usage? TIA.

To the best of my knowledge, the only country to have produced under license German equipment in the years prior to 1941 was the Kingdom of Yugoslavia and they used the Cyrillic alphabet. Though most of their artillery equipment was of French and Czech origin, this can be a direction worth exploring.
As artillery fuzes are really not my field, I cannot help further.

BTW After 1941 the Germans used two Yugoslav facilities to produce artillery ammunition, both situated in Sarajevo:
1) Staatliches Arsenal, Sarajevo, Yugoslavia ("kfa")
2) Staatliches Arsenal, Sarajevo, Yugoslavia Gesellschaft zur Verwertung chemischer Erzeugnisse mbH, Werk Kaufering. ("kfg")

Bulgaria also used German equipment during WW2. Could be export production for them.
