Cheers Coff, mentioning the Prentice brings back a few memories, I joined the CCF, Air Section when I was 14 & a Brat at Windsor School, Hamm. We went to Gutersloh for Summer Camp & had some flying experience trips in a Prentice.
Years later our eldest Son who was in the RAF, was stationed at Gutersloh & then a few years later our youngest Son, who was in the Army Air Corps was also stationed there!!
So, back to Chipmunks....
