Vintage super 8 movie editor in original box

Description

Vintage movie editing machine made by the James Heddon's Sons Co in Dowagiac Michigan.  Not sure of the year but I'm guessing 1950's.  Appears to be in excellent condition.  Plugged it in but nothing happened.  On/off switch moves up but won't stay there.
Not sure how to operate it.
Both hand cranks turn. Money back no questions asked if you are not satisfied.  I will gladly sell to anyone, anywhere, but I only ship to US addresses.  If you are an International buyer you will have to arrange shipping to someone you know in the US. Please feel free to ask any questions or request more photos but try to do so before the last day.  Thanks for looking.  It's rather large and heavy so shipping will be .99 to the 48 contiguous and .99 to Alaska and Hawaii.
