Michael is quite correct, we had both types WRT and WTL. The WRT carried a 10.5m ladder and the WTL carried 13.5m Ladder, however all appliances carry both the 10.5m and 13.5m ladders hence they are all WTLs.

Gents,
As the 2nd pump at Ellon this appliance carried a 10.5m ladder so was designated a WRT, maybe it was initially a WTL when based in Aberdeen originally. It certainly didn't have 13.5m ladder when based in Ellon. Only when this appliance was replaced did both Ellon appliances have 13.5m ladders.
