Re: GPO/BPO 620 plug, 6 way
I've attached a photo of my 6 pole plug and socket. The socket has 'RS' on the fixing bush (obviously not visible in the photo) so that's where it must have come from.
I have also got the November 1992-Februrary 1993 RS catalogue to hand. It lists the following 'BT Type Jack Connectors' :
4 way plug (BT 420) 478-677
4 way socket (BT 84A) 478-683
6 way plug (BT 620) 478-712
6 way socket (-) 478-728
It's interesting that the socket has no BT reference number given (although the plug does).
