My brother recently passed away and I received his favorite all time guitar "Guilda". He purchased the guitar in California from a pawn shop in the early 80's I think. It was in rough shape and he had a luthier do some basic work but left her pretty much in the same shape. He played it in clubs until a few years ago when diabetes caused him to lose the ability to play. My problem is that there is no sticker on the inside although there is an oval type imprint left on the wood. It has a subtle arch on the back also. My brother always said that it was a 50's model but I am unsure the year or the model number. If someone could help id her I would be grateful. It sounds amazing and I will play it and remember my brother no matter what. I am posting some pix to maybe help.
