Sorry, wasn't suggesting it was the aircraft in the pic - I'm thinking circa 78-80. They had 720s TF-VLA/VLB and 707 TF-VLL which was the ex Maverick International 707 N448M -
an interesting saga! I saw it overfly one morning with a very loud and confident howdy on 134.9 as it passed Woodley, "London, Maverick 448 Mike"!
