Well, not "exactly", Mark.
About 5 or 6 years ago, one of guys who's a fellow member of the SoCal Norton Owners Club had one of these Toppers, and I remember him trying to sell it at a one of the vintage motorcycle show and swap meets that they run around here.
I think he was asking something like $1500 for it at the time, and it sat, and sat, and sat all day, and think he finally unloaded it for somethin' like $1200, and I can't imagine that they've gone all that much higher in market value since then.
