Automatic 340 shutter operation
Recently I came across an old Polaroid Automatic 340 camera. Couldn't resist and now it's mine. I have absolutely no experience with Polaroids, though.
Now, to the point: Trying to resurrect the camera I replaced the old Everready 531 battery with 3 x 1.5V button cells. The shutter began to work, but it behaves strange - when I cock it and press the button, it remains open until I release the button. Does it mean my Polaroid is broken? Maybe I should just tweak with the settings?
Any advice would be appreciated.
