It does look the neck has been off before. It was not unknown for guitar salesman to swap Tokai necks from maple to rosewood and vice versa for a customer,( or for themselves) back in the day, especially if they had several models in the shop at the time. Somebody may well have ended up with the opposite swapped around. Originality didn't come into it, Tokais, although well regarded were still seen as a copy guitar.
