Dummy fuze of unknown origin

[super7]

Bought this dummy fuze the other day but have no clue for what type of shell it was used. Fuze has no markings. Overal length is 190 mm, thread diameter 50 mm.
I suspect it might be for a 155 mm shell but correct diagram and/or picture of a complete set showing this dummy fuze would certainly help. Much appreciated.

Regards, Jan

The thread diameter is most likely 2 inch instead of 50mm. That is a very standard size. It has a very similar profile to the older WWII era British fuzes.

Just measured again and it is exactly 50 mm on the thread.
