Salvaged from a “grand-daddy” valve oscilloscope – a Taylor Model 31A
Taylor Electrical Instruments were a designer & manufacturer of test equipment in England
The company was purchased by AVO in 1958 and eventually AVO (which was purchased by Metal Industries in 1959) was purchased by Thorn Industries. A lot of structural changes were occurring in the electronics industry at this time.
The equipment dates from the early 1950’s! see the photograph to view this ugly beast in all its former glory.

After evaluation, I decided that full restoration of this Taylor scope was not a viable project so this is one of the parts I have removed.

CLIX – Shorting plug
Clix (British Mechanical Productions), founded in London 1937
Early 1950’s
Type: unknown
Extremely rare antiquity from mid last century electronic equipment.
Designed to plug into adjacent panel mounted sockets to allow for a change in signal path or manual switching of signals. For example, in the case of the Taylor 31A scope, these plugs were used on the rear panel to determine the X and Y signal paths. See the photograph of this rear panel on the 31A to gain a clearer idea.
NOT for AC or DC power use, these were intended for analog signal routing.
PLUG DETAILS:
The body appears to be a bakelite material, it doesn’t feel or look like PVC plastic. I did the fast rubbing/hot water test and smelt a chemical odour although faint. I then tried the metal cleaner test and a cotton bud comes back with a yellowish/brown colouring.
I believe this reinforces the idea that the body is made from a type of bakelite.
The two pins are solid brass.
Printed on one side of the plug body is:
OLIX

DIMENSIONS:
Pins are made from brass and 2mm diameter
Pins are 13mm long
Pin spacing is 13mm
Body appears to be a bakelite material
Body height is 11mm
Body width is 12mm
The body has the appearance of being hot flowed into a mould
COSMETIC CONDITION:
I have a few of these, all are very clean – shiny clean brass pins and no damage to the body
