I agree with the post above. It is not the diecast category model. The diecast means it is already assembled and painted. In other words "ready to use" and it doesn't mattter what kind of the material the model was made of. The diecast models can be of metal wood etc...
The Magna Models kit is just like the plastic kits for assembling. But the basic parts are made of the epoxy while those other pieces are moulded of the white matal. Below a shot of the kit parts I found via the net.
