The reason 1/30 scale exists is 1/32 was too competitive and the prices too low. The solution was to start a new and larger scale incompatable with 1/32. Unfortunetly W. Britains, Figarti and First legion all increased their scale to 1/30 and the competition is back. Now some Toy Soldier companies are repeating the previous solution to the problem of competition and moving to the new and better 1/28 scale!
FOV would own WWII armor in 1/30 scale if they decided to do so. Polystone armor could not compete on detail or price with mass produced armor like FOV. With Figarti and W. Britains no longer producing armor a real oportunity exists for FOV in 1/30 scale.
The Toy Soldier figures have gotten so large at 66-68mm I use them with 1/25 scale Tamiya armor.
