I've always like marked and unmarked Gayners and this is the first time I've seen one with so much junk. Whatever is in the glass it is all confined to the dome and there is even an underpour to boot.

This insulator was found by John Wilson in Worcester, MA in the old Boston and Albany RR yard near the old Coca-Cola plant and the beautiful Union Station. (http://en.wikipedia.org/wiki/Union_Station_(Worcester,_Massachusetts)

Thanks for looking!
