15cm SIG 33. Sd.Kfz.121/122. "Wrongly known as Bison II".

"After World War II, a scale model kit company produced one of the first retail kits of this vehicle. They called it the ‘Bison II’, believing it to be the natural progression for the earlier Bison I 15cm SPG based on a PZ I chassis’.

This was wrong. It was never called the Bison II during the war but, after the war, the name Bison II stuck. Museums, historical books and other scale model kit companies continue to call this mobile artillery weapon the Bison II."

Seems like another case of M113 "Gavin" ?

Great info @Dercius

"The combat career of the 15 cm sIG 33 B Sfl ended with the British counteroffensive at El Alamein. By December 2nd, all vehicles of this type were lost, mostly for technical reasons. 6 SPGs were captured by the British. Later, several of them ended up in the Egyptian army. The last 15 cm sIG 33 B Sfl was destroyed in 1948 during the Israeli War of Independence. "
