As far as I know, that's the only company (Revell/Monogram) making 1/48th B-17 kits (B-17F & B-17G). Hasegawa and Academy both make 1/72nd scale kits of many different versions of the Flying Fortress, all the way from a B-17B to the B-17G, including a search & rescue version from Academy. I have two Academy kits (B-17F "Memphis Belle" & B-17G "Carolina Moon"), and, although I haven't built them yet, they look great. Very nice detailing, and trial-fitting of the large parts (wings, fuselage, etc.) shows nothing to worry about. Good Luck!!
