Waiting for final confirmation from helpful tech at Mila (and fingers crossed, installation instructions etc!) but it does appear to be an (obsolete) 3-DL.
Mr Grich - fantastic detective work! I can see on the leaflet with the E-Bay hinge the 'HAPS' logo, so we are very close! Unfortunately nothing in the HAPS line has the square plastic cap, although it looks as if all the other bits on the p100 are the same. Many thanks. I will chase up Mila, however again! in case there are some differences.
