The Revell Flower Corvette uses a mold that Matchbox originally created (in the 70's I think) & that Revell picked up when Matchbox got into trouble. No matter what boxing, the sprues inside will be the same. I haven't made it, but have read reviews to the effect that its detail is a bit basic in places. Still, in that scale you can go to town correcting it.
Revell Germany has a tie up with Hasegawa to use some of their aircraft molds & this could I suppose bring about a difference between some Revell US & Germany kits of the same subject. Being seperate now, if Revell in the US ever re-released a 1/32nd FW190D kit, they may well choose to use the old mold that they have, whereas the Revell Germany boxing uses a more recent (& way better) Hasegawa mold.
Only speculation on my part?
