The hull is all made up from plasticard, the gun mounting was carved from balsa and filled with milliput, while the gun is re-used from the original model to make up the L48 version of the Jadgpanzer IV. When I retrieved it a few years ago for a repaint before assigning it to one of my Megablitz divisions, I noticed one of the road wheels was missing. Battle damage no doubt. I'd not done a massively good job converting the ball mount for the MG, but hey, I was only 13 and no doubt in a hurry.
The Airfix Panzer IV always suffered from overlong tracks, these have been cut down and stapled together. They are still fractionally too long, but fit much better than the originals. I was always very pleased with these conversions, and from the side they sit quite like their real life counterparts. A slight gap in the hull is evident here, again no doubt youthful haste (and cutting all those angle shapes was really had), or maybe poor quality welding.
I went with very plain markings (just three balkan crosses) as by 1944/45 the massive production and consumption of German AFVs meant much of the early war heraldry had gone .
I'm glad to have resurrected this model, but I do wonder what happened to its partner. Oh well, lost along the way somewhere I guess.
