It's a common enough model, with fairly predictable performance characteristics, that I think I would leave it just as it is, non functional. If I wanted a PT-26 in working order I would overhaul one that was not new old stock, but still in close to original condition. Which reminds me, I have one of the Canadian versions of this set downstairs, unfortunately I had to repair a crack in the cabinet and paint it. I would save the pictures posted of this set, they will make good reference photos for restoring other PT-26s like where the stickers are located and so forth. It's interesting how they used cloth backed tape to hold the box together.

P.S That seller is goofy and rather overpriced on most of his radios, that Philco was likely the only one worth anywhere close to his asking price, take this little gem for example:

Rare? Worth $79.99? I don't think so. This series of portables was built between about 1955-59 and they built 10s or 1000s of the things, that one is on the older end of that range since it still uses the squiggled "M" logo.
