I just got back from the auction. Thanks for the heads-up.
It was fun to see, though I wasn't buying. There were maybe 200 bikes and many pallets and boxes of parts.
Highlights were a beautiful Benali, a Laverda, several Motto Guzzi's, Nortons, and yes Honda 4's. A very nice 550 four was already in someone's
pick up when I got there.
Serious money was being exchanged; many lots of Norton and Indian parts went for $500-$700 each.
An interesting time. I wish I'd gotten there sooner to see what bikes were selling for. I have a feeling there weren't too many 'steals', judging from the parts sales.
