A set neck Spoiler??? Defretted fingerboard......Hmmmmm I'd need to see the serial # and control cavity.......buyer beware.
Looks to me like an Excel with a Spoiler body shape. The serial number on the back of the headstock is very though to make out.
And as Garyhead mentions above... appears to have been fretted originally.
