The Miles M.100 “Student” was a two-place, side-by-side trainer that first flew in 1957. You can read the wikipedia entry HERE. The high wing configuration makes it an obvious choice for FAC Jet Cat Glider.
One example was built and there were at least three different color schemes for the plane as you can see in the following photos. There was overall silver, white over blue, and blue over white. It was also flown with and without tip tanks. All were found online, and you can click on them to see the largest size.
