Yes, indeed, I did know that you once owned this lorry and it was you I was addressing when I said I maybe close to tracking down the person you bought it from. When I read, in a previous post of yours, that you had acquired this lorry from a bloke who owned "a garage somewhere in Somerset" but that you couldn't remember where, I set the hounds to work and I may have a result, and hopefully, a few 'photos soon. Or maybe not.
John, thank you for the info regarding the blue Constructor now owned by your friend, Sean Reed. I think I'm right in saying that, like many other Scammells, this one past through Geoff Rhodes hands. I believe Geoff brought it from someone who would take it to shows and challenge all comers to a tug of war hence the ballast compartment on the back. Geoff sold it to the bloke who ran
an approved school near Stoke as mentioned in a previous post. For a number of years a vintage and steam rally was held in the grounds of the school and the Constructor was employed towing a water bowser round to service the steam traction engines at the show. At few years ago I saw this Scammell advertised for sale. Maybe that was when Sean Reed bought it.
