Kaja-3 (20MT2)

The multi-line telephone device Kaja-3 ('kaja' means 'echo' in English) was manufactured in 1977 by the experimental factory "Vihur" in Tallinn, Estonia. It has 20 line-selector buttons, a handset and a rotary dial on the front panel. The phone handset and electronics are from Latvian VEF TA-68M phone, integrated into the device, the main electronic board is "handcrafted" in Vihur factory Tallinn. The device has additional built-in speaker and microphone, allowing it to be used also in hands-free mode. The front panel is covered with black imitation leather (dermatine) and features attractive stylised enamel badges of Vihur and Kaja-3 brand names.

This rare example of Soviet-era Estonian industrial design was saved in 2026 from the Põdrangu collective farm (Põdrangu sovkhoz) in Estonia. In fact, the same collective farm had a complete set of different Kaja devices, including a dispatch console, all manufactured at the Vihur factory in the 1970s.
