So I searched the archives here and couldn't find any firm comments ("R22" is too short a search term) so wandered the web until I found Colonel Joe's past comments on the subject. VERY illuminating! I guess the chances of this being anything but a fake are just about non-existent. I'll give him the bad news!
Cheers, Steve
