{probably Model 2438RZ1, Chassis 24G26Z1}
Looks like it is complete except for a few tubes.
Has all the correct knobs, both chassis, adn back cover. The antenna system is in place (red twin line), and I see the wood brace for the metal back cover too. Not too rusty either.
Its exactly like the one I restored -- my guess it uses the 16EP4 picture tube.
