Another condolence for your brother's plight and that your task is not an onerous one. Please take care of yourself as well, caretakers need caring for also.

One thought about the task ahead for you came to me this afternoon, U.K. Classic Lightweights, managed by Peter Underwood, has his bi-monthly Cambridge Lightweight Newsletter and I have seen him write blurbs about someone in your podition, and in encouraging others to help identify bikes, or to promote estate sales or such. It could be worth your time to use the email contact link on this website. He is well thought of and from my readings in the site, knows how to dig out the details of bikes and components. Nothing ventured-nothing gained, best wishes on the task ahead, I hope you will update us on how things proceed as time passes, for both your brother and the bikes.
