Frank,
I have followed your various posts and threads here and have admired your skills, willingness to offer help to anyone asking and the history you area part of in bicycling. I am a road bike guy but this bike is so important to MTB history and your friends needs so great I wish you all the best in the auction. I would think Zap and the other guys would be glad to help from reading their stuff all these years. they seem like super people to me.
I am not well off but if there is a way to donate to the helping of your friend please let us know how we could do so. I would gladly make a donation for them. Bicyclist are neat people and your efforts just reinforce this to me and I am sure others here.
Bill
