As an apprentice in a Strowger GSC, I remember the 'wow' factor in watching an '11 & over' final selector self-stepping vertically when it found the first 10 lines busy.
After TXE2 electronics, transmission, and retirement, I still have fond memories and respect for the design features of a UAX13.
A few days before it closed, I taped the sound of Arley (West Mids) UAX13, later made into an MP3.

Plenty of Strowger is still working in preservation in the UK including UAX13s. Five preserved railways still using Strowger 'for real' .
I have a working 1929 UAX plus I've got UAX12s and a UAX13. Also got the last working 'Strowger' from the BT network - Foula exchange in July 1995. See
'BT Digital Exchanges - a Timeline'
There's a working TXE2 at Avoncroft Museum at Bromsgrove.
Even BT still have an electro-mechanical exchange working in London but not allowed to say anymore about it - yet!
