Maybe in the future, but three turret bases to use none sounds like a real waste

Cor, not this old chestnut again. Schuerzen were intended to counter the Soviet anti-tank rifles, which obviously were not found in N Africa. They were nothing to do with anti-tank rockets, as the only type the Red Army used was captured Panzerfauste. Obviously they did appear in the west too but that was probably more about it being easier to standardise than to design vehicles for one specific front. And obviously units did transfer en bloc between fronts anyway.

Anyways, I'm interested in the "complete interior" part of it as I just recently started kit-bashing together a complete interior for a PZ IV G using the donor-interior from an earlier kit with the new Border kit. I hope to beat this new release to market. And oh, by the way: there is an entire series of pics showing a tank depot in Norway being surrendered to Allied forces that was chock-full of PZ III variants with full schurtzen. In short, they were everywhere. And the Soviet anti-tank rifle from that time period was only effective against vision ports and dummies who stuck their heads out too far. As such Schurtzen would be ineffective overkill on that as they were too thin to do much more than slow the round before it spanged off the armour plate.

You seem to get your wish with them showing a CAD of the Maybach engine, though not clear if it's included or separate add on. LINK That engine is by Border Model, not RFM.The more the better though!

The US sent the Soviets small numbers of what we call the bazooka, sometime in late 1942 or early 1943. The Soviets also had access to captured panzerschrecks, which was based on the bazooka's captured from the Soviets, and/or the US in Tunisia.

I believe the cones are for bending Starr antennae, they look a bit large for Jgpz IV.

You make it a standard piece of equipment on the tank and just send the tank wherever. North Africa just missed the introduction of schurtzen. They surrendered before the first tanks produced got to them. But there were a couple in Sicily and lots at Salerno. In North Africa the Germans encountered a hollow charge rocket launcher though no skirt equipped tanks made it there. The bazooka. And don't you know the real reason for schurtzen? To disguise the old Pzkpfw III and IV with sheet metal to imitate the round turret of a Tiger! That way the Allies will think every German tank is a Tiger! (Actual rumor recounted by armored division veterans) Tracks and road wheels, especially when it makes up two thirds of the side silhouette are great targets for high caliber rifles. Some Russians supposedly were experts at breaking the tracks. Maybe another rumor but as an old tank gunner it's what I'd try for.

Read somwhere that the Allies reinforced their tanks with steel meshwire after invasion of France. Maybe first "slat-armor"? Any pictures of such vehicles?
