Mark, thanks for that info. The 20" RK floor tom shell I'm working on has "Chxxxx" written in script with pencil with 16"x20" underneath. For the life of me I couldn't read what it said. Mahogany interior and pencil hard to see. It had a lug hole drilled through the word also making it a puzzle. LOL must be "Chrome" that would make sense.
My pleasure! The factory workers wrote all sorts of things inside the Slingerland shells. Mainly to instruct other workers what type of hardware to install. Really adds a personal touch.
