I can't find it either Riotonsunset. Lots of double neck models during 1975-76, but most of them incorporate an SG body style. The only Fender style double neck I have found is a 12 over 6 configuration. It is the 2375.
I've never really understood the bass-guitar double neck. I view double necks as a stage instrument so the 12-6 configuration makes perfect sense to me. But who switches from bass to guitar during a song? If you're not going to switch instruments during a song, why would you want to carry all that weight?
Double neck players enlighten me
