In answer to a question on this subject that was brought up in Old Ron's Bar & Grill, here are a few examples of the most desirable plastic Philco sets.

Model PT-35, August 1939 (1940 season)
Note how this model is a clone of the TP-10 above; only the decal is different.
There is also a variant of this model with brown grille, dial pointer and knobs. Other variations in color may exist.

There are others, but the most desirable ones seem to all have Tenite grilles like the four examples above, and usually bring $100-300 or so on our favorite online auction site. Usual disclaimers apply (price depends on condition and/or desirability, not all auctioned radios bring high prices, your mileage may vary, etc.).
