Aoshima showed 1/700 HMS Dorsetshire, Flower class corvettes (!), and a York-class cruiser.
Flyhawk showed 1/7++ HMS Lance, a destroyer, probably just a repop of Legion with some detail differences. Some 1/700 photoetch - for Trumpy Hood, Queen Elizabeth.
Hasegawa: 1/700 IJN destroyer Asashimo and what appears to be a harbour diorama with drydock. There's a Soya in 1/250 (yes, 250, not 350). Some 1/700 linoleum decks for IJN heavy cruisers (Mikuma and Maya?).
Very Fire showed a 350 Missouri.
Someone (Yamashita hobby?) showed 1/700 IJN destroyers Ushiho, Akebono, Shikinami, Mutsuki
Modelium showed shome smallish vessels in 1/700, looks like AOS-5201 Hibiki, some kind of civilian fishing boat or small transport, and a tugboat (?)
