Fascinating thread. Freon's post #52 is in the hangar at Eaglescot if I'm right. Barry won't part with those gliders. I own WT905, she will be airworthy again in 2015 and I would love to hear from anyone who flew her in the ATC.
The list on post 156 has her written off in 1955. Slingsby did most of the repairs back then and have no record of her going back for repair and I can't see any old repairs under the fabric, but would love to know more.
I've got 15,000 flying hours and the T31 is still one of my favourite mounts.
