The Trav-Ler dates from about 1947, books out at 30.00-40.00, but condition and cleanliness is everything....recapping one of those is a 10 minute job, let me know if you need caps. The Magnavox looks like about a $5 garage sale job, but it might go well, although I'd be surprised if it fetched more than $20.
Now, let's talk about the Philco
Look for the words "Philco High Fidelity" on the front just above the speaker. If you see it, GRAB IT! Those sets usually bring $300-$400 not working. Count the tubes, give me the model number, what have you. For Philco, 1938 is pretty much universally accepted as the best they ever made, so no matter what it is, you're sure to get a great set!
