Thanks all - I will try Volvo Heritage.

I've also now spotted that in 1975 there were two Volvo Price List's issued - one in March, only for the 200 range, and one with "Prices Effective from 15th September 1975, for 1976 Specification Cars" that includes the 66. (It was £1945 on the road btw!). So that does hint that mine was in the first couple of months of production at most.........

This could turn out to be interesting!
