Small size “microfine” slide rule by Pickett from the USA. This is the later all plastic 160C-T (white) with 7 scales on the front. It is in unused condition, in the leatherette sleeve that still has the promotional sticker on it…as well as the manual (in English) inside. it measures only about 15 cm or 6 inches long. The sleeve is beautiful as is the manual with hardly ant signs of storage. Check the attached video on how to work your vintage man tool : slide rule operation instructions!
