letter scale

This letter scale is made by B. Holsboer from Arnhem, the Netherlands. Probably, B. is the initial of Berend Holsboer. The starting year firm of B. Holsboer is 1867. The measuring scale of 100 grams has a stripe of measure per each gram. A funny detail of the Holsboer letter scale presented here, is the subtle information that is added on the chart of 100 grams. Near 15 is engraved 1, at 50 is engraved 2 and at 100 is engraved 3. This letter scale can be dated to the short period 1867-1871, see here.
