It could be a Balashka, Did your grandfather give it to you?
I believe it is a Mike Roberts "ITS GEORGE",these were before he made the side seams,some are marked or labeled some are not.I could be wrong but I bought over 200 of his cases and it looks familiar. I have never seen a schon case and the engles ,kelly,and fellini had leather tops.Hangemhigh is more of an expert on cases,but as I said I owned 200+ of these Its George cases and I respectively disagree with the man from Tennessee

Other than the signature it does look just like the Thomas. And Tommy it is a little bigger than the Kelli. That's a Kelli it's propped up on in the pics. Tommy this is Jerry from Chattanooga, how's things going with you?
