Here are a couple of scans of ancient prints.
Dez is in the red child seat / sitting on the wall, the Head of History at Maidstone Girls' Grammar School is in the yellow one.
Mrs. Wow is a hippy.
I think those pictures were taken in the autumn of 1982, just before Shirley Hughes asked us to model for the Alfie / Annie-Rose books
. That would make Ellen about 1¾.
Edit: I've realised I'm wrong. The bike with the red child seat is the same bike (silver in one photo, black in the other) and in the wrapped-up-warm photo, Mrs. Wow is riding her ancient BSA.
The respray / overhaul of my Claud Butler and the purchase of Jan's Viking (from Alf Hetchin!) occurred after I was knocked off my bike by the Southend Mayoral Daimler in July 1982 so that photo must have pre-dated that event. Ellen was born in Jan 1981. There were no leaves on the trees in that picture so it was taken at the earliest in the Autumn of 1981 and the latest, February 1982. Ellen would have been at most 13 months old.
The first picture is taken outside Canewdon church, the second outside Paglesham. It was clearly a lovely warm sunny day in the latter and my bike must have had time for its overhaul. I've forgotten whether we bought Jan's bike before or after the compensation cheque from the Council arrived, but that would almost certainly be August 1982.
