Just begging for a Hotel California rendition, this Fujigen built Twin-neck is otherwise known as Ibanez 2402, we often see Greco versions too. CSL was Charles Summerville Limited, an importer with stores in the north of UK. I bought this guitar in 1990 from JG Windows in Newcastle-upon-Tyne and have only ever needed to perform routine maintenance on it. The lower neck bridge pick-up is a 1980s replacement and is apparently a DiMarzio - as the original Maxon units sound so good, it has never occurred to me to change anything about this guitar - it is solid, reliable and despite the weight, very comfortable to play. Difficult to date precisely, but having seen a lot of 70's Fujigen products, I am putting this one at 75-76.
 
How heavy? 5.65kg (12lbs 7oz) so pretty heavy! But a sturdy strap is all you need to be Don Felder for 7-10 minutes at the end of a set. The original case is present and correct, the hardware is all original and perfectly aged but functional.
 
But a Gibbo is going to be 8 big ones, an Alpine White 1976 Nashville is probably going need a mortgage. This ought to be close enough if you need to be Don Felder. Fujigen really knew how to worry the guys in USA for quality - I bet this one outlasts the real ones.
