This is me playing the best sounding guitar I have ever owned for slide. I purchased it in 1980 w/missing logo. The body is mahogany. Based on the components and the serial# G16635, I'm pretty sure that it was made by Valco around 1964. The components and shape are consistent with Airlines that I have seen but I have never seen them in this exact configuration. I would like to replace the Logo but I want it to be correct. Any thoughts or opinions would be welcome.
