After the launch of the armoured locomotive BR 57 a line of kits of BP 42/44 trains armoured cars is a logical step. But why "Geschutzwagen", this one apparently is a command car?

can we PLEASE have a different trailer

The Geschutzwagen would be nice in 1/35th but I question the need for the Marder III as Dragon pretty well nailed that one down.

Trumpeter released one in 2009. http://www.trumpeter-china.com/index.php?g=home&m=product&a=show&id=1078&l=en

The Marder is a slight derivative of the ex-Tristar kit, so it probably doesn't represent a large investment of effort for HB. KL

Could you make a whole armored train, or would that be inappropriate? (Were the cars not all available at the same time?) I like the look of the cars, but they appear to be pretty easy kits, with the bulk of your time spent on the paint scheme and weathering. Or am I mistaken? Definitely cool kits, but a little pricey.

You could indeed make a complete armoured kit, as to the availability of each kit at any particular time: who knows. Unfortunately (and completely ignoring the cost) you'd need a shelf about four meters long to display it!

I'm glad they are putting the train out in 1/72, as I've always wanted to build one, but given the cost of it in 1/35, as well as it's being so large when finished, that was nonviable.
