The Stilltime Collection (see postings below, titled 'Historic photos of AC's') has the two photos below. I believe they show the Hon. Victor Bruce and his wife Mildred. What they are doing, and why waving as if to gain attention, I don't know. These are likely factory publicity shots taken at Thames Ditton, and they may have been used to show the dropped hood on this 6-cyl. Aceca open/closed coupé.
The model was advertised with side glass. Most (all?) had wind-up windows, so I wonder if anyone can tell me the purpose of the door strap? Was this to raise the window glass, before the introduction of winder mechanism and internal handle (as clearly not on this car)?
