I recently aquired a Kodak Ektar 127 mm lens for 4 X 5. It came on a lens board w/ a small solenoid to trip the shutter.It's a cute little thing, about an inch long, cylindrical, chromed, with power posts extending from the side of it. Can someone tell me what voltage it is? (I was able to activate it with a 9 volt battery but not a penlight and I certai nly don't wish to burn it out.) What is the usual power source and how many trip s will I get on one power source? Thanks
