This looks really nice. It includes the Instructions, actinic paper, and list of plate speeds. It functions by putting the paper from the red package in to the back of the circle seen in the left part of the photo. Expose it light and time how long it takes to match the control color. Then use the calculator. I cannot imagine being a photographer in that era.
PLEASE CAREFULLY REALLY READ ALL OF THE FINE PRINT BELOW BEFORE PLACING YOUR BID
I primarily sell used photo equipment. As such it is usually not 100% perfect. I try to advertise items as
honestly as I can, but if you are looking for something that is 100 % perfect it might be better if you
buy the item new. Also, I do NOT use stock photos.
