Vintage Slide Rule from 1970 Technology published by Simpson & WilliamsHere's a great nostalgic retro gift, and now a true collectors piece for anyone technical. This is a late Faber Castell slide rule from Germany in the original hard case. This model is the 111 54 Dramstadt, the redesign of the earlier 1 54 model and the latest increment of the 111 54. It has 10 scales. But don't ask me how to use it!! G+, case worn and taped. Slide rule in good working order. Name etched on back of slide rule.
