While visiting family this weekend, I was checking out my cousin's recent Guild acquisition. It is a Les Paul style with a pick guard an P90 style pups and my first thought was bluesbird. He's thinking blues90 based on pics in a guitar book that he has. We can't figure out exactly what it is or when it was made. The s/n is CL002626, which isn't in the range listed in guilds s/n pdf. Anyone got a clue? TIA
