USED
Removed from some vintage radio receiver equipment.
Tested (wet rub test and the 'sniff' test - formaldehyde odour) and confirmed as Bakelite material
UNIDENTIFIED MANUFACTURER - Male Plug
Circa 1950's based on the equipment it was removed from (British made too!)
Material: Bakelite (Black)
4 pins
Male
Arranged in a circular pattern but not as a complete circle so that the plug is effectively 'keyed)
Pins are 2.3mm diameter x 10.5mm length
The pins are HOLLOW, this is because the method of attaching wires is as follows:
Strip back the insulation, insert the wire from the rear of the socket and 'sweat' solder into the pin at the front end of the plug. Heat from the iron is not an issue because Bakelite withstands much higher temperatures than modern 'standard' plastics - the pins will not become misaligned while you are soldering.
It looks to me as though the body is entirely one piece, I could not see a way to get 'inside' the plug.
DIMENSIONS:
Front of the plug (pin end) 15.5mm diameter
Rear has a small flange which increases the diameter to 17.75mm
Total length of the plug (including the pins) is 18mm
COSMETIC CONDITION:
USED
CLEAN
Bakelite body has NO cracks or chips
NO discolouration
I have carefully removed any old wire strands from inside each pin, leaving the pins hollow and ready for insertion of new wires.
The pins are shiny and clean, not oxidised!
This plug has now been completely sealed in a clear plastic packet, awaiting the new owner!
