120 Mortar LOT number identification

Hi every one.
I have one 120 mortar photo.
I want to know about the year of production.
Please help me


What 2340 dose mean?

What are the markings on the incremental charges, on the propelling cartridge/primer and on the fuze?

This one here has features if Israeli made rounds.


It was made by Soltam Ltd. of Israel. Some of this ammunition was supplied to Iran before the Iranian Revolution (1979) and during the Iran–Iraq war (1980-88).
