P4297?
The top view shows the structure of these trolleybuses whilst below from a similar angle is the completed 409. The seating configuration of these vehicles was B26+30D.
At the bottom 419 is shown, without destination blind, at the Cointe terminus in the Place du Batty. There is now a roundabout at this location, terminus of the first trolleybus route in Liège.
