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"!
