Charley,
I didnt see you at the auction, saw Bill wandering around...the very first thing I drooled over that was there was the Yale bikes.....I got some good pics to prove it. If you need any help with your new piece of motorcycle history let me know as I believe I have some printed literature and general history on these bikes, no doubt yours in particular. I have a friend that offered the seller more for those bikes then what they sold for a few months back, if you ever get tired dusting it let me know and I should be able to set you up with a buyer for profit.
