letter scale
marked:
A.C. v. Rijn
den Haag

On the brass measuring scale of this large letter scale the name A.C. v. Rijn, den Haag is written in an oval at the top left. This was probably the user of the letter scale and not the maker. In Meten en Wegen No. 151 from September 2010, the pages 3597-3599 contain an article by Rein Kok with the title Een brievenweger van Kipp uit Delft (Translated: A letter scale by Kipp from Delft). The 200 gram letter scale described therein has the name P.J. Kipp & Zn. Delft and J.W. Giltay Opv.. And that combination of names was used from 1887 to 1916. In addition, a nameless and unbranded scale of 1000 grams is described, this scale is also attributed to Kipp from Delft. In the book Weegwerktuigen of the Staatsbedrijf der Posterijen, Telegrafie en Telefonie, for short the PTT (The Dutch state-owned Postal, Telegraph and Telephony Company), the image section contains this letter scale in figure 131. This book compiled by J.N. Bosch dates from 1962. No maker or brand is mentioned in the description. These scales are said to have been used by the PTT until 1950. I saw another copy on the internet, the owner replied that it was marked with RIJKSMUNT.
The company A.C. van Rijn was an Electrical Technical Bureau active from around 1912 to about 1924. This company probably did not trade in letter scales, but was probably the user of this letter scale. A.C. van Rijn was later active in the firm Handel-Mij Electro-Metaal, certainly until 1972.
The bearings on the suspension point of the letter scale shown here are missing, but can be seen in the figure 131 mentioned. The letter plate has been reattached to the suspension bracket with soft solder, it is probably not the original letter plate. The weighing range of 1000 grams is subdivided per five grams. Various parts are marked with the number 43. The highest point of the letter scale is 52.5 centimeters.
