Finding this Gibson made me wonder about my other one. I believe it’s an L 50 but I am not sure if the mother of pearl inlay is on the fretboard make it a more specific model. Also the serial number is 397130 which, I believe makes it a 1953 model but, I could be wrong about that too. There seems to be a lot of different information online when it comes to serial numbers. I tried to take a picture of the model stamp on the inside. On the subject of cases neither one of these have cases. I got the L-50 from my Dad, who got it secondhand when he was in college and it never had a case. Still doesn’t.
