Comment On the back two stickers:
  • "Humboldt-Universität zu Berlin, Inv.-Nr.: 4698/76 Mikro" which was placed ontop of a similar sticker with the inventory number 4699/76.
  • Metallic sticker, partially missing on the left side: "Electronic calculator elka 103, Exporter: ISOTIMPEX, Power supply: 6V D.C., Made in Bulgaria" Note that the sticker really says "elka 103" rather than "elka 130"!
