Libor,
I understand the reasoning behind your company's decision, even if I am a bit sad about it.
If it helps keep the idea alive however, here is how I would pitch it to any company that makes photoetch parts:
Idea: Universal modern armor accessory set
Scale: 1/35--the broadest segment of the armor market
Specific model targeted: None! This new set would be a universal accessory set--similar to Tamiya's (or Hobby Fan's) modern accessory sets. This ensures much broader market appeal for the product, since it is not tied to the popularity of a specific model.
What to include: Use existing designs to minimize R&D costs. For Eduard, that would mean using portions of sets 35565 and 35844 for the ratchets. The set could also include the ratchet straps, CIP panels, and other generic modern armor accessories (padlocks, ammo belts, shell casings, weapon slings). All of these items have already been developed and can be re-purposed for use in this set.
Hope this helps!
