For your consideration, here is a Westinghouse Projection Lamp Bulb DFY, Blue Top, 1000 volts, made in the USA.  The bulb looks new and the filaments are intact.  It has not been tested though.  The box has wear on it, is missing some of the printing and an end flap.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (243.301e-.10bx)
