$20 OBO.

I built the 17cm Geschutzwagen kit from Trumpeter awhile back, but didn't use the engine and transmission sprues, because they're totally hidden inside the completed kit.

There are three sprues, which you can see at the review of teh newer kit here, but they are exactly the same. See images 5, 7 and 14 (K, L and M). I'll double check the instructions, and send along any other parts that look related.

$25 plus actual shipping (won't be much, they're small and light). I'll include copies of the instructions for these bits.

I also have the 1/16th King Tiger kit, and these parts look like a miniature version of the engine included in that kit. Does anyone know which came first?
