I have to update my previous post, because I just found out over at Hyperscale that Mike West (Lone Star Models) is working on a 1/48 Sparrowhawk kit.

I also forgot to include two other aircraft I'd like to see in 1/48, the B-18 Bolo and the B-32 Dominator.  I have seen a couple of projects online to scratchbuild the B-32, I think the size of the completed model would be between that of Monogram's B-29 and their B-36.
