Max;
COOL stuff! I'm a wurf fan - built a couple wurf vehicles and have ambitions for a couple more...

This is going to be GREAT! A wurf track!
IF you may be interested in "developing" your boxes and rockets some...
You actually have lots of options with those wood wurfkasten... most were of course made of un-finished wood and thus probably lighter-colored - but some were painted - usually a darker green, IIRC from some museum specimens. Because they were banged around and stuff, they did get dirty and scraped-up. (But, unlike their steel cousins, these boxes were pretty much one-way trips and not recycled, I think)
IF you have any small black and white "label" decals - these boxes typically did appear to have small paper shipping tags or labels (on the front "closure board" when shipped, and also on a side / top and maybe on the rear end). I'd guess the kit might have those decals, or paint some on?
The rockets came in different colors - most appear to have been painted either a very dark green, or something very close to the darkest version of "dunkelgrau", or - more rarely, "dunkelgelb". I mostly use a "weathered black" color for mine... In most cases, the rocket had a white-letter stencil around its front end which identified what it was ("28cm Wfkp - Spg" or something like for the Hi-X type - the most typical rocket) (there were 28cm and 32cm rockets - used the same box but with some spacers for the smaller rocket - and some larger rockets came filled with a type of napalm... these had filler-ports on the sides. But I degress!). Some kits (my experience has been with the Mirage kits...

come with (lousy to put on) decals for this label detail...
While being shipped, and right up to the minutes before they actually launched them, wurf rode in a closed box (with the center board across the nose-end) and without that nose fuse installed... that fuse was screwed into the rocket only after the box was opened and mounted in its launching frame (part of the arming dance - that and inserting the ignition squib and wire into the motor end holes). The fuse was apparently enameled black in color.
(FYI - some really nice pics of a relict wurf and box are to be seen on the DishModels.ru site!)
So... you can play around some with these on your build! Boxes mounted "closed" with no fuses yet, "open" with no fuses yet, open with fuses, empty (fired and all sooty) but still in the frame, etc.! (Note: rockets could be fired one at a time with all racks loaded, or fired as a group in a "ripple" order. So having an empty box among several full on the racks is perfectly good). And if you have any spares - closed and no fuses!
Just some suggestions! I look forward to seeing this completed with great anticipation! What will the paint-scheme be?
Cheers!
