Newly renovated. Not sure about items your inquiring about
This museum has been newly renovated with items from Paul Revere's ride, the Revolutionary War, and local tribes. It includes the lantern from the Old North Church.
Mr. Stinson, My husband and I recently visited the museum, and we believe we saw such instruments, but the exhibits change throughout the year. We saw Thoreau's desk and other unique pieces too. Here is a link that shows the exhibits: https://concordmuseum.org/exhibitions/ **This museum is worth making a trip for!! I promise! **
