Goofy style here . never seen one till this
Looks like a variable inductor tuned by a brass vane.
Variable tapped coil, rather than tuned. I've built crystal sets when I was
a kid that used a very crude form of this, with a fixed cap across it made
from wax paper and aluminum foil, and a slider made of brass that was
screwed onto a board and just scraped across the coil's windings to tune the
stations.
