It probably does but these bulbs cost seven or eight pounds and don't last long, expecting something to be available on E bay, people are damaging fittings to accommodate 2 pin types http://architectures.danlockton.co.uk/2008/07/21/how-to-fit-a-normal-bulb-in-a-bc3-fitting/

At places like Wilko you can get 2 pin holders for about 1.50. Cheaper to change the holders and have done with it. The landlords won't know till you've moved out.

3pin ROUND pin 13A plugs and sockets. And the fuse had a screw thread on one end, and was in fact the live pin.......
Don't think there are many around, now. -- Please donate to our appeal at www.donatetobreastcancer.org/nakedbikeride 155 raised so far Thanks Ian

I'd not heard of 13A round pin plugs. I have seen images of the rectangular pinned ones where the earth pin is horizontal, and the live and neutral pins are vertical, though. They look odd!

two sizes of sockets, both with round pins. Presumably different ratings. The back boxes weren't flush like nowadays, but screwed to the skirting boards, or just above. Easily knocked and smashed when moving furniture.
And big brown bakelite light switches, the wiring for which was in a metal conduit which disappeared up into the ceiling. Electricity had not been included when the house was built.

There were a number of competing designs, different from each manufacturer, before British Standards settled on the winner in 1946 (which I think was mostly MK's design).

There's also one with a T shaped earth. However, these are current products, specials, to enable separation of incompatible supplies from standard appliances, such as where you have a clean earth or UPS supply for special equipment, or you want to provide sockets just for cleaners, or similar.

In my neck of the woods the early plugs were all Wylex as they were manufactured in Trafford Park these were circular with a round centre earth pin and a flat pin at either side 1 horizontal and 1 vertical. They came in 2 sizes 5a and 15 a.The 15a had wider pins to prevent it being plugged into a 5a socket but you could plug a 5a plug into a 15a socket.They also made a 15a plug that would allow you to plug a 5a plug into it.Later these were replaced with MK or MEM 3 pin plugs similar to today's but the pins were circular and IIR MEM did have a fuse as the live pin. As for the 3pin lamp only one I ever saw was a Philips special for an emergency light this was 15w 240v with the pins at 12.- 7 -5 o clock to prevent wrong installation.

Like others have said, just replace the lampholder.

3 at 120 degrees makes the bulb have 3 orientations, which doesn't work with two rear contacts.
At one time, three prong bayonet cap was used for the smaller mercury vapour lamps with external ballasts, verses standard 2 prong ones for internally ballasted mercury vapour lamps (or ordinary filament lamps). This stopped accidental relamping with a standard mercury vapour lamp when there was no ballast in the base of the streetlamp (and the resulting lamp explosion).
Some busses and trains used screw fitting lamps with a left hand thread, supposedly so they weren't any use if nicked. Modern screw lampholders are so crap, they probably would work in them!
