You are more than likely right, where I was confused was I thought there would be only one set of steel moulds for this kit, and at some point Academy re-tooled them for the improved kit. So shouldnt only the "new" version be able to be produced/cast?
There must be more than one set of moulds then I guess - surprising as I always heard those are terribly expensive?
As noted it doesnt matter much as more than likely we will see a new kit not too far off....
