Formica came into being around 1913. There were many many industrial uses besides the familiar countertops which came about later. Westinghouse used it for fan blades in the 20's: I have one of those fans.

That radio is definitely from the 1920's, as has been previously stated. The history of radio communications would tell you that: the form of the set, the tubes it uses, the fact that those tubes weren't available until the early 1920's, and that broadcast radio didn't come around in force until the early 1920's. Having a 3-gang condensor is different and advanced for the day: most TRF consumer sets of the day were "three-dialers." In the mid twenties and later Atwater Kent and others chained or belted together three single condensors in attempts more or less successful to make single dialers. The problem was making the three tuned circuits track together. Since RCA had a stranglehold on the superhetrodyne patents, not many wanted to pay them the royalties to make the superhets which largely solve the tracking problems along with other advantages, so the TRF's persisted until the early 1930's.
