Like new condition very specific and wide size slide rule by Pickett from the USA. This is the model 6 in white (T version) for statistica quality control (the later version ca 1960’s). I still comes with the plastic wrapper around the slide rule, in the original sleeve in great condition, as it the slide rule itself. It also comes with the 2 Pickett basic manual but it does not have the specific manual ( a scan is available here by the slide rule museum). This slide rule measures about 31 cm or 12 1/4 inches long. Check the attached video on how to work your vintage man tool : slide rule operation instructions!
