A.W.Faber-Castell TR3 Combined Slide Rule and Calculator. The calculator uses 4, 1.5V button cells, type Duracell PX825 with a diameter of 23.2mm and a height of 6.1mm. PX825s are no longer manufactured and are difficult to obtain. I currently use 4, Duracell LR44s with a diameter of 11.6mm and a height of 5.4mm. These are smaller and a little ingenuity is required to make sure that they are centred and make contact.

A.W.Faber 369 (Dietzgen 1779), Made for Lawrence and Mayo, a London based producer of Scientific Instruments a descendant of which is still in business in India. The rule has a plane wooden back with 369 and Made in Bavaria stamped into the wood. The Cursor has Lawrence & Mayo London stamped into the lower edge of its frame. Scales 5in//A[B,C]D||15cm [S,L,T] 15 - 30cm scale in Well. I cannot see the Faber name on the rule therefore its place among these rules is solely my personal opinion
