Description

vintage pickett slide rule 84 Inch.
A complete fully functioning Picket N1010 Trig slide rule. Only it is 84" in length!!!!
Picket made these large wall demonstrator slide rules for the classroom. Up into the 1970's this was the tool used to do a lot of calculations. Learning to use one took some time. I have available the 84" version of the iconic N1010 trig rule. Made of plywood in eye-saving yellow. The rule is 84" in length and 10" in height. Great condition for a item used in school every day for 40 years. This one was owned by a biology professor at a prestigious school in Nashville Tennessee.
Shipping only available in lower 48 states!
