Charcloth - there is a growing program in WW II history within the History Department at Florida State University in Tallahassee. They've been gathering materials for the last several years, and taking many oral histories. I do not know what their present projections are, nor can I advise you about present facilities. If you would like me to look further, I'd be happy to do that.

Was your Uncle's ship a military vessel or a civilian charter? What exactly do you mean by "charts"? Are they just nautical maps, or do they contain course plots and similar notations that can describe that vessel's operations? Is there a log book, etc.? These are the kinds of questions a serious collection would want answers to, perhaps before accepting the materials, but certainly in deciding what to do with it if they accepted it. There is no question that the materials had great significance for your uncle as mementos of a traumatic event in his life. But that, in and of itself, doesn't mean that they necessarily have any historical value in the broader sense.
