A Bakelite Radio Once Owned by the Shirelles? Prove It.

Q: I am excited to ask you about my Bakelite radio. Although it looks like an ordinary worn radio from the early 1940s, it happens to have come from the home of the Shirelles – the historic girls singing group of the 1960s. This is the radio that the girls sat around the kitchen table singing along to at home. I know this because the sister of one of the group members was a best friend to my best friend. She gave me the radio and told me the story. It must hold some historic value for certain. How do I go about obtaining written provenance to prove this radio is the radio from the home of the Shirelles? And once I can do so, does it, in fact, hold any monetary value?
