Sold LOT of 17 GE # Number 11 PhotoFlash Lamp/Bulb Class M NOS

Asking $60 plus shipping.
This is a LOT of 17 new, unused GE number 11 photoflash bulbs. Each bulb was tested with a multimeter and verifying continuity. A GE number 11 is screw-base (also called Mazda Base or Edison Base) bulb, the about size of a 25-watt appliance light bulb. About one stop brighter than the #5. Approximate 2,400,000 peak lumens, with 18,000-22,000 total lumen seconds output. For use in a 7" medium base reflector.

Are these compatible with the Graflex flash ?
Thank for the effort

As I understand it, they are. I just added a bit more to the item description as well. Please let me know if you have any other questions.
