I got this Peavy case with an Ibanez TR-80 on Fleabay. It was missing most of the padding. I needed a case for my Brice (currently awaiting a headstockectomy and a white refin). After cutting away the plastic in places it fits, needs to be refoamed. Usually it's wrapped in a sheet.
The Brice has an extra fret clear of the body compared to a Gibson 'Bird and the headstock is a Fender shape so a case like this might fit a real 'Bird or replica. It's 50 inches end to end outside dimension and 5 inches thick so it's deep enough to fit a Brice angled headstock.
