I know of a two-seater in upstate NY that has been sitting in a barn with an easy riser since the mid 80's. I have yet to see it for myself, but I am going to check it out next month when I visit my family. All I know about it now is that there are "trees growing up throught the wings!" It's obviously been neglected and I imagine that the engines are trashed. I will send some pics and try to get the serial number.
