letter scale with loose pan

letter scale

This letter scale with a loose pan of aluminum was made by Jakob Maul. The JM mark is placed in the tin vertical standard of the black frame. The base of the scale is made of steel strip in stead of cast iron. This is harder to break and it's cheaper. A frame of steel strip is not as fine. The range is 250 grams. Per 5 grams a division stripe is given. The chart with the white figures on the black background is good readable. The readability is positively influenced by some tricks. By the use of smaller sized noughts, space is created for larger sized decimal figures. By omitting the figures for hundreds, again space is created for larger sized decimal figures. Somewhat odd is that this resulted in a chart that presents the same value several times, for instance 20 grams.

The full chart

Only be looking thoroughly and by comparing with neighbouring values, it will become clear whether it's 20 grams, 120 grams or 220 grams. This letter scale resembles strongly the letter scale described earlier at pendulum scale. This aluminum pan is more solid by the folded edge, the shape is also more beautiful. The cross-shaped holder for the pan maintains its shape better because it is made of steel. The ealier described version is made of weaker aluminum. Below some more photos of this letter scale.
