By High command's assault gun plan, the Zrinyi type*
assault guns were divided into two branches the*
Zrinyi 105 (Zrinyi II) and the also developed*
Zrinyi 75 (Zrinyi I) which was planned to use the new*
75mm 43M gun as a tank destroyer.*
The Zrinyi had a 105mm field howitzer modified for*
vehicle use built into a widened Turan hull. The*
front armor was 75mm. The rate of fire was slow due*
to the separate shell and charge but this allowed*
greater quantities to be carried. The stability and*
maneuverability had improved significantly compared*
to the Turan and the howitzer proved to be potent.*
The problems around the new gun delayed the Zrinyi 75*
and the Zrinyi 105 assault howitzer entered service*
first and earned a good reputation on the front. The*
production continued with the Zrinyi 105 until the*
75mm gun became available. In early 1944 a few Zrinyi*
75s were produced but numbers are unknown. In summer*
the factory was destroyed and all production was*
reduced to minimal without machines. In 1944 assault*
guns were equipped with armored skirts on the sides.*
