Hello all! I need some help identifying a Guild that's on my repair bench right now. Everything about it looks as if it's an X-175B, but the neck has dot inlays as opposed to the trapezoidal blocks. As for the label inside, it doesn't appear to have had anything written on it. According to this, http://support.guildguitars.com/downloads/datingyourguild.pdf, the serial number dates the guitar to 1959. Any help would be greatly appreciated!!
