Hi Everyone! First posting so I hope my info is clear. I have a Buffet R13 that I purchase from a store back in 2006. I've recently graduated college and now am trying to sell it off for some much needed funds. For identification purposes, I found the serial number on the bottom joint but for some reason the upper joint does not have a serial number. I tried checking the normal spot (on the back printed horizontally near the bottom of the top joint) and pretty much everywhere else but it is no where to be found The serial number is in the 540XXX range!!! I'm trying to remember what may have happened to it when I first purchased it but have not much recollection from 9 years ago. Is it normal for a Buffet R13 not to have a serial number on the upper joint in this range? Or would there be a reason it doesn't have any identification?
