Hiya Gerald,
The young Lad is Gordon Thompson, Harry’s Son ! he was about half that size and probably 9 or 10 when I first came across him in '69 with his Dad in their LAD Reiver up and down the road to London ! They did some right “midnight flyers” on Smiths traffic ( same as me as well with loads of Libby’s 
) On a different note it looked like one of Jed’s Cranes came unstuck off the A7 to-day and if it hadn’t been for the trees he would have ended up in the Loch ! Cheers Dennis.
