I can?t give you a guarantee of course...
..for me all looks legit for an 80s TE-50, except the logo positioning which looks a bit odd
can?t help you with more details than already listed in the previous posts
there are a few things that would be good to know (photos of the pickups, cavities, neck heel stamp)
pickups should have TEB stamped underneath but stamps can wear out or pickups can be changed
wiring (switch, pots, capacitors) looks exactly like on other mid 80s TE-50s that I?ve seen as I said before
as you see there is also a little ?treble bleed? capacitor next to the green one. that is part of the original wiring Tokai used back in the 80s
