| This page shows plugs and socket for which
help by others is appreciated ! Help refers to: 1. Material in the collection that is unknown to me and useful information has not been found on internet or elsewhere. 2. Material that must exist, but is very difficult to find. For example, the museum has a plug, but the matching socket is missing. Your help to find a missing item or
unknown information is greatly appreciated !

| Bakelite contact
plug with an unusual large - 27.5 mm - spacing of slots for 4.0 mm
pins. Halfway in between the pin slots is a plastic ring. This "dummy"
slot has a 3 mm offset. It seems likely that the plug has been designed for an, unknown, appliance with two power pins and "dummy" pin to assure a single plug orientations. However, left and right contact do not have AC L/N or DC plus/minus marks. Volt and amperage rating are not indicated. |

Logo and marks: • Circle with large S. May be related to manufacturer. Several companies use(d) a similar logo, but a logo with an identical typeface S has not been found. • MPAD mark: 78 = Hugo Krieger & Faudt Elektrotechnische Fabrik in Berlin (could apply to the cast only). S = Bakelite reinforced with sawdust. • VDE: German certification mark. • HKB: probably an older type Hugo Krieger Berlin logo. |

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 |
