Looking for my Grandfather's guitar- 1966 Gibson J-45

This is a total long shot. I am trying to locate my grandfather's guitar. It is a 1966 Gibson J-45 with a Cherry Sunburst Finish. He purchased it new in 1966. Upon his death in 1996, he willed it to my Aunt, who later gave it to my cousin who sold it to a local music store for cash. The guitar was then purchased from a store called "Mic'd Music" in Texarkana, TX in 2012 by someone from Florida I believe. I do not have a serial number currently but may in the future. This guitar belongs in my family and was sold for little to nothing as a senseless act. I am reposting this ad all over in hopes of a bite. If you have any information, please inbox me. Thank you.
