This page shows plugs and socket for which help by others is appreciated !
Help refers to:

    has not been found on internet or elsewhere.

Greek Tripoliki socket
For decades Greece had a, nowadays rare, type of earthed sockets and plugs, known as
tripoliki mpreza (sockets) and tripoliki visma (plugs).
In 1989 Greece switched to CEE 7/3-7/4 (Schuko) standard for earthed plugs and sockets.

A Tripoliki mpriza was for many years missing in the collection, but thanks to successful investigations by Michail Kritsotakis the museum has now two old type Greek sockets.

See Greek page. for more images and information
