Hi Simon,you,re correct in saying it was,nt local. ( maybe foreign trucks were a clue aye ) 
Was taken at the French / Spanish border at La Junquera in the late 70,s.
I was there for the week-end in my non sleeper ERF when i met the old boy from Wisharts in his flash 88.
He was in his 60,s then if i remember correctly, dont recall his name though.
Regards Tony
