If you look over the dispatcher's left arm, you'll see a rectangular case containing multiple buttons (replacing Morse telegraph keys) to acknowledge in service taps (2-3) from the firehouse. Above that is a telegraph register and take-up reel which appears original issue(1910-1920). To the right is a borough radio microphone, a telephone probably purchased by Mayor LaGuardia, and an early iteration of a borough status board.....of course unused.
