Scientific Instruments Company 1570 Electro Vector Slide Rule S510 1961
SIC 1570 Electro Vector Slide Rule. SIC slide rules were manufactured for Scientific Instruments in Berkeley, California by Japanese manufacturers Relay/Ricoh and Concise. SIC had custom models which added scale labels to the cursors, a handy, yet costly, technique which was never duplicated on other brands or by other manufacturers. Note that on slide rules that have the SIC Diamond Logo, the rules have serial numbers but do not have the pi (?
) gauge mark on the A and B scales found on earlier slide rules without logos. The linear SIC Models numbers are normally a Relay model number with an extra zero (Relay 102 = SIC 1020). The SINCO logo was used in 1965. SIC 1570 Electro Vector Log Log (early). Made in Japan by Relay/Ricoh for SIC - 1961.
