“Instant Set”

Data:

• 13” long, 5” wide rectilinear slide rule
• Slides are aluminum with laminated paper glued to it.
• The body is made of a dense cardboard stacked and glued in multiple layers to give room for the pieces to slide.
• Marked a.o.: “Instant Set”, “SG323”, “Designed by Wall”, “Shift Register Stage”, “C2686 Address” and “CV706 Address”
• Probably 1980's

Question:
