Thank you! It seems like I've possibly found Leigh Christian from Blue Turtle - http://3dleigh.com/
I'll try to contact and get some exact information, may be we get lucky this time :)

Yep, the images are on his site under history, so no doubt about it.

"The first commercial game I worked on was Rolling Thunder in 1986, I converted the graphics from photographs of the arcade game for the zx spectrum 48k. There were no mice then and the pixels were plotted using the arrow keys on an Amstrad. I created many of the graphics at my friends house after school before taking my first full time job at Codemasters in Leamington."
