right landing gear collapse

[kragby]

1972 Serial No. 00025 T337G. Normal approach, downlock thunk didn't seem right ( but had green light) so did a tower flyby. Tower said 3 down ,looked normal, cleared to land. Touchdown seemed normal, second later right leg folded back and we went a short ride on the wingtip into the grass. The wheel collapsed against the closed gear door and kept the belly from scraping.
No prop strike. Some wing tip damage to plastic and end rib, and rear dorsal fin
