[big-all]

is the green dot to draw your attention to the problem

 

[johno12345]

thats a nice grain

id be slightly concerned there but would guess its old.

The green dot is probably to show that it has been PIRd in the past

.....Or to say "Use this outlet to burn the building down "

Bureau Veritas like them dots, usually red for fail, green when tested ok.

Dots were also used to indicate Phase of Supply, in the traditional world of Red Yellow and Blue in days gone by....

You would see a Red, Yellow, or Blue adhesive dot applied to a switch or socket etc....

C'mon, Rob, you've whetted me appetite now...

Where's a piccy of the inside of the Albany?

 

[Lectrician]

Dots are often used to indicate which item recieved the 'random removal of accessories' during regular PIR's. Different colour each year. Don't see it done so much these days (or regular PIR's )

BV dotted all our sockets to show that their martindale tester had shown 3 amber neons. That must be good then

 

[Nige F]

Socket is fixed to a wardrobe

 

[333rocky333]

I would say thats a bar/pub panelled wall.
Mk albany sab were quite common then, not cheap though.

IS this the dark spot on the top left of the socket looks Burt

thanks

I'd say the scorch mark was from a previous socket front..
enough heat to do that would almost definitely damage the white plastic bit and melt the laquer on the brass.. not to mention discolouring th brass itself..
