Is this simple radio worth the huge effort it needs? - SBR R1 - Part 1

A new patient on the bench, but this time one in near-terminal condition: an SBR R1, a small and simple tube radio, using only 3 tubes.
The big elephant in the room however is the sad state it's in. A huge crack in the cabinet and a ton of rust and dirt on the chassis. Is it even worth still trying to fix this radio? Let me know what you think...
