Hi guys,
Just to upgrade the post these are the specs for the ST-70 guitars I have actual photos and dates listed - not to be confused with ST-70S ( an entirely different Model)
1024145 12=3 OW X ST-70
1024205 12=9 YSO X ST-70R
1024238 12=3 FO X ST-70
There are a couple more but with no details or serial numbers so I cannot confirm them.
These 3 I can. Look at the matching body stamps as the neck stamps match them.
All 3 are December build, all 3 end with 'X', all 3 have 1024xxx serial numbers and all 3 are a different colour.
I have found most consistantly that from 1981, ST-50 bodies tend to end with 'Z', ST-60 with 'X' and ST-80-up with 'A' [also stamped on the neck]
To my mind, the ST-70 was an upgraded ST-60, which seems to be a theme with Tokai at the time, hell the ST-70S had 2 different serial numbers and a painted headstock.
regards
Peter Mac
