Yes Its the 1979 vintage version of the UK Bridgeport Textron set-up.
Previous version is WD 145. Next version is WD 153 dated 1981.
No significant differences in any of the Textron 1970's to early 80's era drawings. Mostly component layout changes. The few wiring variations are functional equivalents so its not too hard to puzzle out but it does make life harder when sorting the efforts of an ace sparky from Bodgitt & Bend Ltd.
