Minicord shutter speed range and function demo

Finished cleaning and reassembling the shutter of my minicord camera. I haven't done a speed test on it to see if it adjusted, but it's interesting to see this odd little camera in action. The aluminum rod on the left is connected to a flat disc piston that slides down a cylinder bored into a brass block to provide slow speed retard. As the speed dial is turned a vented needle valve drilled into the cylinder is unscrewed. This allows air to enter the cylinder more quickly for higher speeds. theres also a cam on the speed selector that pushes down the shutter trigger arm which increases the shutter spring tension and increases the shutter speed.
