Nora Lewis, dresponded with the following:
Dear Mr. Mead:
Thank you for your interest in the collections of the Georgia Historical Society. Unfortunately, the Japanese suit of armor was lent, in the 1960s, to a museum that ultimately went out of business and it was never returned to the Georgia Historical Society. As far as I know, no one has ever been able to track it down and it is considered lost from our collection.
I'm sorry I don't have better news. If you ever hear anything about it's current location, please pass that information on to us.
