Gem

Bands: AM

Tube Lineup: 57, 58, 47, 80

This Gem is a 4-tube cathedral radio with no tags or labels anywhere for manufacturer and model number. The dial escutcheon on the top reads "Gem". The circuitry is a T.R.F. (Tuned Radio Frequency) design similar to a Climax 457, but I am not certain that the Gem is even related to the 457.
