I manged to purhase an old book about the origins of the Standard Vanguard. Whilst is mainly covers the Phase 1, there are elements of the Phase 2 and it does have a lot of period photos. I'm not sure if anyone else has a copy of the original book and I'm not sure if I am allowed to reproduce the content here in digital format, if anyone knows why I cannot display the images here, let me know, until then, please feel free to enjoy a piece of history.
BTW - I bet you didn't know that the Phase 2 Vanguard had the first commercially produced and fitted Diesel engine. Facinating what gets lost to history.
