My Gretsch Chet Atkins serial number is G127515 > December 1967 and I believe it is a G6119 Model. I see pick guards in several places (Ebay, Amazon..) for the G6120 and it looks like it will fit, but absent any measurements in the adds I have no way of knowing if it will fit. Advice on what to order and other model numbers if more than G6119 will fit. My guitar is in good condition and has not been played to any extent in over 30 years. I purchased it second hand in about 1980. The strings were replace about a year ago and it tuned up okay. It remains mostly unused but my interest has returned to playing some guitar and I'd like the Gretsch to have the protection of a pick guard before I make any regular use of it.
