BassManWoo

Hi, I’m interested in adding the "Title" to my Gibson collection of Tobias Toby Pro’s and was wondering if during the build or at any time was it customary to stamp the bass used? (Please see attached) I was told by the seller that it was stamped at the factory. I find that hard to believe. None of my Gibson Tobias Toby Pro’s have such a stamp. Also, how is the age of the bass determined by the serial number? (311515268) Thank you. V/r Louis Tobias Toby Pro 6.docx
