A vintage case draws immediate attention from collectible guitar cognoscenti- which may or may not be what you’re looking for. This Lifton dreadnought size case is correct for ~1940 Martin D-18 and D-28 guitars. It shows plenty of edge wear and use but remains structurally solid and appears to have its original handle and latches. There is some tape on the edge that will require careful removal. This vintage Lifton will round out the package for your prewar Martin.
