Further comments The very first slide rule I bought on Ebay, in October 2005.

Compared to Faber-Castell slide rules, this slide rule is manufactured in an extremely cheap way. No celluloid but laminated paper. Plastic cursor. The wood is very light.

Very typical is also that the slide is longer than the stator.
