Looking for a case for a case. More specifically, looking to get an Anvil-type case to hold my grandfather’s 1930’s tenor guitar, in its (no longer all that sturdy) case. So a solid case, foam-lined to fit and protect the guitar in its original case.

Anyone have experience with one manufacturer or another? This doesn’t necessarily have to be flight-certified, just want the aging instrument and case to be well-protected and supported.

Let me know. Thanks.
