The carve of the neck heel looks like the type on set-necks not the standard Gibson bolt on heel. Plenty of those 70s set neck blanks have been available over the last couple of decades. Someone could have picked up one of those and built a bass around it explaining the decent woodworking on the neck and lack of hole filling VS the middle school shop class work on the body.
Kinda what I was thinking, except I'm not sure a set neck would have enough tenon to convert to bolt... also might change the scale or at least the point at which neck meets body.
The easiest explanation would be Ripper neck,.... and it seems maybe doable; I didn't remember how far out the neck joint goes vs older models (that way they could keep all the G series body blanks the same I guiess; production efficiency).

also, re logos, even without decals, silk screening is super easy - none of y'all even DIYed yer own band Tshirts? I mean this is even just one color - no need to line up the next screen for the second colour, which is the hard bit (and I've done that).
