I've read the same thing Trek420 said--that the XO-1 is a highly desirable bike among some circles. I've read long posts somewhere about how people wish they could find one, wish they'd start making more, etc. You have really got a treasure on your hands!

My touring bike is a Waterford 1900 is similar in character to the XO-1: lugged steel, 559 tires, barend shifters, and drop bars. It's the most comfortable bike ever, though a bit heavy for fast club riding.
