Nice preheater! These are huge Tulamp ballasts. Judging on the braided insulator on the wires, yours might be from the 1940s. My shop light shown in my bulb collection album dates to around 1945-1946 and has the orginial GE Tulamp ballast. The pic of mine is here:

May all the great lighting technologies have their place in history.
