oh boy I see some familiar models in your collection
my collection has about the same size, though some different models included-as written mostly HM and Century Wings;
I have added a two IJN warriors yesterday, a D3A Val from Skymax (the Ceylon strikes one) and an A6M-3 from Witty (Rabaul Air Wing); it is interesting to see them side by side with their USN opponents, the Devastator, Dauntless and Wildcat
Patrocles, the HM models are great! dont expect build quality a la highly customized plastic kits with days of effort put into them, but for diecast models, they are really great ones! if you look into the Langley Raptor, be prepared to get some Testors colours and Elmer´s White Glue to fix a serious gap under the canopy on the port side, but other than that, even the Raptor is a great model!
I suggest you try and get the Vandy-1 F4J from HM to see what they are capable of doing
if you want some really really GREAT quality jets (F-14s, A-6s, A-7s or Blackbirds), watch for Century Wings.
I do have a Crusader and a Tomcat from them and rate them as simply amongst the best models in my collection, together with "Stinky", the new HM A-26A and the new VT-8 Gay Devastator from Skymax....
