By researching prior sales and google, I believe this to be a Lyon and Healy Camp Uke though it does not say Lyon and Healy anywhere on it that I can see.Got this info about a similaruke atukulele.org:Your ukulele is definitely a Lyon and Healy Camp Uke. They are pretty durable little instruments and can sound pretty good. There were a number of different models made through the 1920s, all with round bodies. The \"Camp Uke\" name was registered by Lyon and Healy in 1923, but they claimed first use in 1921. Lyon and Healy used unusual woods on some of their ukuleles. The Camp Ukes were made from Nyssa wood. The 1925 Lyon and Healy catalog features three models of Camp Uke all \"made of two-ply, laminated Nyssa wood\". It goes on to explain that \"Laminated means that the wood is two layers, the grains cross-wise, carefully glued together. The one layer reinforces the other. Nyssa wood is strong, not easily cracked, and possesses wonderful vibrating qualities.\" The catalog states that the Camp Ukes are \"exclusive Lyon and Healy products, made in the famous Washburn factory\". The three models sold for $6.00, $7.50 and $10.00. In the early 1920s, the fanciest Uke sold for the same price as a Martin Style 0, $10.
I will try to answer any questions as honestly as possible. I am not a instrument specialist by any stretch of the word.
