At first glance I initially thought this was a bogus auction for some slapped together parts bass that someone was calling a Gibson simply because of the headstock truss rod name plate, but upon further research I've determined that this is actually a lefty Epiphone Power Bass that's been been stripped to bare wood with the Epiphone logo removed from the headstock. So while it's technically not a Gibson, it is a rare Epi, though modded obviously:

And the real deal Epi Powerbass:

I'm not sure why the Epiphone link isn't working anymore, but here's a link to another picture of a real Power Bass:
