Dave,
We have a Grob Twin Astir that just got totalled by AIG (the gear ripped through the hull). Theres nothing wrong with either of the canopies and I'm certain they will sell this for parts when it goes up for auction. We have a Board meeting Tuesday night. I'll let you know if the final paperwork has been signed or not by our club's President to transfer title to the insurance company.
Best of luck,
Chris Schrader
