There is one more country about which army it is very poorly known. It is army of Persia. Here at a forum already there was an information about Persian tanks and armored cars. The information about aircraft too can be found.
But, I can not find the information on artillery of Persia at all.
I know, that on arms were available:
75mm mountain guns Bofors mod.30 - 120
105mm guns Bofors mod.27-????
75mm AA guns Bofors mod.30/37 - 20??
75mm mountain guns Skoda mod.39-
37mm ATG Skoda
?????
I know that in Czechoslovakia 350 guns have been bought.
There can be somebody has the information what types of guns and mortars were used in the Persian army in WW2
