Other than Friul and Modelkasten, I can't seem to find workable tracks for the pz.IV early with open horns. I know that some exist, but can not for the life of me remember who makes them. Can someone point me in the right direction?

I believe TriStar makes a set with the hollow guide horns.

Tristar makes mid and late tracks, in 1:35. I can't find any of the early tracks made by them.

Cyber Hobby / Dragon makes them I think?

Bronco also makes track sets.
I bought about 4 sets of Dragon / Cyber Hobby Winterketten tracks before for the Stug III.

Would these be the ones? Comes with two different guide horns,a bit fiddly to work with but should look nice.RZM is great to deal with.

Matt, are you looking for 36cm or 38cm tracks? The early tracks for the Panzer B thru E were 36cm with open guide horns and are made by Friul, Model Kasten, Tristar, Spade Ace, and Dragon. The Tristar and Dragon tracks may be hard to come by. I think the 38cm with open guide horns are made pretty much by all the same manufacturers. Now mind you that 36cm tracks are almost always referred to as 36cm but 38cm tracks are often referred to as 40cm tracks (the width with track pins installed). Just FYI.
