Well, depending where you classify the Norf/Sarf divide I am usually considered Norf and I have not seen it for yonks but had seen quite a bit before that, I suppose the elder artisans with all singles and N to Rose and L to switch then switch to rose it was second nature to them until the loop in loopout and T & E became king, the S & E or S without E was often used only on the few two way switches, one way switches were all T & E (Feed and Return so to speak).I'm fairly confident you can still buy the harmonised equivalent, mostly likely Oop North, where they seem to go ape for it.
