Since I figure prominently in this picture and since it seems like it's been here a while, I'll shed a little light on the subject. This in NL11T (44-74425) in Sanford, FL around 1974. Don Plumb, I believe, had recently purchased it and had it in Sanford with Johnny Bolton's "Hi Honey". It was later painted with the color scheme in Case 256 and eventually went to the Netherlands in 1994. What I don't know is where it was in between.
It looks like 11T by the H prop. I thought it went from Bubba Beal to John Herlihy to Jack Flaherty etc
