JustCruising, although we have not met, I am a good old friend of Eric's and also live in Kalamazoo. That is why Scottly initially contacted me about your good intents. When I read your story, I remembered what Eric has told me about your cousin and I am sorry to hear he is not doing so well.
Best of luck selling your cousin's parts. I love to hear about rare old parts finding their way to the owners of the bikes they belong to...thus making more old bikes back into a useful thing of beauty, that they were when they were new.
