The Panzer III F was very common in the early period, so I grabbed a box of the Plastic Soldier Company Panzer III F,G,H. These were fairly easy to put together, though not nearly as nice as the PSC Panthers - these are an older box and PSC is getting better with each new release.
I used some Battlefront and Dom's Decals on these to represent B Co., 2nd Platoon, First Battalion, 35th Regiment, 4th Division. I based these with the Battlefront Early/Mid War German Armor and highlighted with German Field Grey and Stone Grey.
I had some difficulty figuring out where to put the Divisional markings. I could not find a great picture with the marking on the front or rear. In the end, I found some information that basically said that there was little standard practice and that even among Companies there was quite a bit of variety. In the end, I picked nice visible places front and rear. I did not have decals small enough to put on some of the side marking I had seen.
