The Sea Hawk kit has a multiple past. I first saw it in THFRO way back in 1988. It has appeared in Revell boxes in the 1990s and Accurate Miniatures (the guys know for the awesome Mustang, TBM and B-25 kits) as well.
I don't think the kit as a whole is is that valuable unless there is some Tom Clancy/Red October collector's market out there. The kits have been reboxed, reissued on several occasions.
The Red October with the sonar lump may be valuable to the "what if" crowd. It sets the kit apart from the regular issue Typhoon. I may be wrong, but I think these are actually DML/Dragon kits.
I've got the complete line of 1/100 helicopter kits that included the SH-60B, UH-60, HH-60, AH-64, UH-1 and AH-1G.
