I bow to your superior knowledge about the retirement of the Lincoln. I based my statement on my (older) brother telling me that when he went to ATC camp at Lindholme in 1960, they'd just retired all their Lincolns to the fire dump. Certainly when I attended camp there a few years later, there was no sign of them; they had Varsities and Hastings, although the latter were grounded because of a structural problem.
