Hi Roger, welcome to the forum !
Fender double bound Tele bodies were offered by Fender in the 50's,
so it should have been offered by Tokai with a maple fret board option.
It is a 1982 TE-70 YS finish example.
It's difficult to be certain whether or not body + neck are both original with differing 2=14 body vs 2=5 neck codes, but I think they probably are both original,
since both codes start with the numeral 2.
The 5 number neck plate serial # format belongs to that neck style in 1982 and it was the final year for that Tokai spaghetti style logo .
I have seen another TE-70 YS with a 60's model range rosewood board and it too had a 3 barrel bridge.
I can't confirm if either shipped from the factory this way or not, with only 2 examples.
3 Barrel bridges are typically found on TE-80+ models but there are exceptions to this.
The 8 screw scratch plate is correct for your serial #.
Pickups should have TEB inked on backs as you reported.
TEA pickups were used on TE-80 and higher models.
The person who scribbled the TE-120 may have confused your double bound example with TE-120 natural finish double bound 1 piece Ash body
examples that have shell trim along the top binding and are coincidentally equipped with 6 barrel bridges,
another bridge exception example.
TE-120's were never offered in YS finish.
I hope this answers some of your questions without posing more than you began with.
