I have my grandmothers ukulele. It is a Weymann. The wood is extemely thin without much interior support. There is a yellow band around the outer edge. The model number is not on the flat surface of the head where the tuners are, but rather on the "thickness" edge. The numbers are 41515 on the left and 116 on the right. I could not get a picture to load. I'll try to add it to my profile. Anyway, I would like to know where to find info on this. What type of wood, how old, who made it etc. I'd appreciate any help you can give Thank you Frieda.
