Another beautiful piece inherited from my grandfather. A bilateral postal scales. Not sure of the year, welcome any suggestions.
Markings on the back: OEST.P. 1766; UNG.P. 16742; D.R.P. 112860.121631
According to this site: "the markings above repersent four patents: the Austrian patent (OEST.P. 1766) was granted to the firm Balduin Heller's Söhne from Teplitz in Czechoslovakia. The application was made June 24, 1899, the patent was granted April 1, 1900. The Hungarian patent (UNG.P.16742) was granted to the firm at January 4, of the year 1900. The second German patent (D.R.P. 121631) dates from March 29, 1899 and was also granted to Balduin Heller's Söhne from Teplitz. Therefore the scale is dated to c1900."
