Hi Scott,
Good meeting you at New Castle last month. the old girl was looking good!
Most of the ASW-15s and -17s imported in the early '70s came in without bags and were fitted with Smiley Bags which Jim Smiley (AH) had made by an airline survival equipment service company (life jackets, rafts and the like.)
I dealt with them about 15 years ago when I was restoring my ASW-17, and if I remember correctly, they were located near Raleigh NC. Unfortunately, I do not remember the name of the company and all the documentation went with the '-17 when I sold it.
Check with John Murray at Eastern Sailplane. At one time, I think he had a source for Smiley Bags but I don't know if he still does.
See you next year at New Castle Intl, if not before.
