1 Larkey 3 weeks ago Hello all, Im very glad to find such a group and hope to enjoy and contribute for a long time to come! I just bought my first vintage Gretsch, the metal headstock plate is missing so i dont know for sure, but im fairly certain its a 6120 Nashville, The serial number is only 3 digits and very hard to read, its either 522 or 322 i think... Though the machine heads look to be original, thats to say they dont look like they have ever been removed, I cant find any other tuning machines that look like them on any of the old Gretsch guitars Ive looked at. Also, there is no embossing or writing on the pick guard... no Chet Atkins signature. I know it could have been replaced, but did they produce guitars with out branding on the pick guards at all?
