Recently purchased a set of Australian wooden and broken cellulose acetate models. When they arrived, there were several wood models with the same numbers you find on the cellulose acetate models. i.e. The Zeke cellulose DOD model has an "E9-2283" identifier under the wing. The wood Zeke model has the same "2283" number impressed into the side of the fuselage.
I was not aware of the existence of official (?) wood Australian models. They could be similar to the US's school boy program, but having the same number impressed into the fuselage as the other models makes me think these could be an early Australian DOD authorized model. Anyone ever seen any of these before?
