Definitely keep it.
Back in the mid '70s someone gave me a Philco TRF radio chassis. Then I found a speaker to fit it, and got the thing playing nicely. The cabinet to the thing had rotted to pieces, according to the young lady that gave me the chassis. It was in her grandparents' barn. I shelved the radio and speaker set, hoping some day to find the right cabinet for it....
Fast forward to a year or so ago. I was in downtown Pittsfield, MA on a Sunday morning after having just done a concert piano tuning at a performance hall there. I was window shopping, waiting for the hardware store to open, and noticed a gutted floor-model radio case being used as a window display prop. Very pretty. I stared at it for a long time, noticing the knob hole configuration, and recognizing that it might fit the old Philco. I could not see around the back of the cabinet for a brand sticker, nor could I get close enough to the escutcheon around the dial hole to read it.
But on a following weekday I went into that store and conducted business. The cabinet bore the Philco name! I paid cash and took the cabinet home, resolved to make it work with that chassis. It took some time to find the chassis, as I hadn't laid hands on it in well over 20 years. I finally found it and (drum roll, please) the chassis fit in perfectly!
Maybe somewhere out there is a Dumont with a rotten cabinet to make a fine guts donor for that beautiful cabinet shown.
