Up for your consideration is a vintage C. F. Martin EST. 1833 ukulele. Needs some TLC. It feels solid - nothing wiggles. There is a crack on the side that feels like it went through - about 2" long. The long scratch on the back does not feel all the way through. Still sounds good though.There are some spots on it - do not know what. The knobs look burned but they are not - just old. No idea about the screw on the lower front. See photos for details....Feel free to ask questions This belonged to a man named Mervin (Melvin? Marvin?) Stang who was in a band in the 30's in California.
