Hello....I just inherited a speed graphic camera with a 3 Cell flashgun..(original SW light saber prop type)...including a 5 inch and 7 inch reflector,,,

..my question is,,,what type/model of bulb does this accept??....and......does anyone know where I can get a couple? ..and for the 5 inch reflector? --since it adapts to a smaller bulb...

Thanks for any help here...

All of the Bold Type labels at the top of this page and on the home page are links. Some information is buried some is not. Some information has multiple paths, some single paths, and some sub links are dead, so:
http://graflex.org/flash/technical.html ( the price info is definitely out of date).

Hit the home page, click the links, and be surprised by what you find.

thanks.

Simply put, the 5" reflector takes a bayonet base (e.g., "standard" automotive like no. 89 or no. 3001, IIRC), and the 7" takes an "Edison" screw base, like a household light bulb.

Where to get them: how much do you want to pay? See uBuy, et al.
