Your best bet is to keep it and enjoy it. Otherwise, if you want to sell it for the top dollar, the tubes, particularly the 45s, are probably worth more than the whole set, I'm sad to say.

Yes, most radio manufacturers of this era (which only spanned 4-5 years) tended to "package" their filter components (choke, capacitors) in a metal box, the excess space inside often filled with tar, pitch, wax, or gutta percha. Fortunately, most of these boxes have no "buried electrical nodes" so it is possible to bypass the internal caps with small modern replacements installed out of sight under the chassis, making sure that the wires to the original potted caps are disconnected.
You could alternately bake out the potting (if it's tar, wax, or pitch) and stuff the box with the new parts, but this is messy, time consuming, and even more of a marriage hazard than the antique radio hobby itself is.
