GHH 106 N sed atki borderer rigid

Hello all , after any info or pics of said vehicle was the first truck I ever went in aged about 13 in the early 80s.
Was owned by j f rileys of lumb in rossendale at that time .
I know it’s a ■■■■■■■ reg maybe was a tractor unit before being turned into a rigid , it’s all just out of curiosity if anyone can help cheers
