(3) Dozen Flashbulbs GE #5 or Sylvania Press #25 Or Both: These #5 and #25 bulbs are loose or boxed. Each lot is 3 dozen. They were the most popular used flashbulbs ever. Today there is only one manufacturer in the world that makes flashbulbs, Meggaflash, in Ennis, Cork City, Ireland. When the Sylvania Company closed its last plant, on St. Patrick's favorite island, the employees had a bright idea. They went together and purchased the plant and kept it going, and kept their jobs, ergo, Meggaflash. They only make 3 types of bulbs; two large bulbs for still photography, and one long duration bulb for high speed movie photography. They have customers all over the world.
