- I dropped one of these from the top of a ladder in Grantham ATE in about 1983. The LTO made me replace all the bust parts (most of them) and readjust it. Took me about 40 hours.
A high level of expertise was required to work on this equipment and it required constant maintenance.

- Early during the change to solid state exchanges, selectors like this were available in the London technical junk shops, and I bought one for £7 to play with. All the wiring was the same colour, brought out to a multiple plug at the bag, so I had no option but to strip it all out and make up my own circuit. I got it to work as a 100-line exchange with some extra relays.

- The last in the chain of First, Group and Final selectors. It is shown here on a test stand for faulting when removed from its working rack. It has ten levels and ten rotary steps thus giving access to 100 subscriber no.s, however, although difficult to see from the photo, if it has a WS (wiper switching) relay, it could access 200 subs. I was a TO (Technical officer) working on these and other Strowger kit throughout the 70's and early 80's.
