This is a combination of Jarlang's 1/72 Diana armored box conversion and the tracks and wheels from one of Bergman's 1/200 half tracks. The rest I created from line drawings and then pieced everything together. I will post separated files at later time.
History:
The ’Diana’ was a conversion of the Sd Kfz 6 5-ton half-track tractor mounting the captured Russian 7.62cm gun (FK 36(r)).
Panzerjager-Abteilung had its anti-tank ability strengthened just before Rommel’s attack on the Gazala Line in late May by the arrival of the Diana.
Fitted with captured Russian guns, six of these vehicles arrived in late January 1942, and three more in February.
All nine were assigned to 90th Light Division on March 8, 1942. The British nicknamed these self-propelled guns "Diana". They proved quite effective during the heavy fighting against the new British Grants, and during the assault on Bir Hacheim. By June 22, 1942 when Panzerarmee Afrika captured Tobruk, only two were listed as still operational.
However, about five were kept running until the second Alamein battles, and two were captured and put on display by the British.
