You are correct on the plastic releases. There are other kits from some small manufacturers but those are all resin.
My guess is Dragon didn’t go down the early alphabet because they couldn’t reuse the running gear sprues from the Ausf E and later kits, as well as the many ‘only on this Ausf’ parts they couldn’t reuse. If they can’t make it from 3-4 previous kits, they probably won’t make it.
Sure Petro, I have a rather unique way of finishing my mufflers. I first apply the Tamiya putty and extra thin cement mixture and stipple it on to give the exhaust some texture. This is followed by a light coat of brown spray paint from a rattle can, any brown paint is fine. I then stipple on various rust colored powders dry followed by a spritz (what’s a spritz? Lol! not a full coat but like a mist coat) of Testors DullCote. Here’s where the magic happens…Lol…Right after the spritz of DullCoat, and before it dries, I dip it into Isopropyl alcohol and let it air dry. The alcohol reacts with the DullCote and a nice white residue is created. If you don’t get the look you want just do it again with powders, DullCote and alcohol dip. The white residue simulates the look of metal that gets really hot like exhaust systems.
For the dullcote, i am assuming a laquer finish, not acrylic?
i ask because Testors Dullcote is what i think of with that term. I have both laquer and acrylic types i can use to try it out.
