If I can get my hands on a few 1:76 or 1:72 scale PzIV turrets from model kits it'll make life easier, but I don't really need to buy entire model kits - I'll need at least 4 PzIV turrets in total, 2 for this railcar and 2 more for the Panzerjagerwagens (flat cars with a single PzIV turret) that will be at each end of the train. I even looked at Plastic Soldier Company 1:72 PzIVs as a possible option but unlike the Shermans they don't include extra turrets
