AC440: Faber-Castell Slide Rule No. 57/88 Students Advanced Reitz Model, boxed.

Date: c1952

Size: 11 3/4 inches by 2 inches.

Before the days of the electronic calculator, budding 'O' level students were all armed with a slide rule such as this.  It is boxed, and in excellent condition.  The rule itself is undamaged, and the only thing I can find to mention is a split in the end of the box lid.  There is a name that has been written on the box tang, but his is normally covered by the lid when it is in place.  The rule has indices for K A [B Cl C} D S T1 T2 L, and the slide has 6 marks including ones for kW and HP.
