Hey Ian,
Both those colours on the 427 were available here too, the red one was the standard from 1970 to 1973, and the mustardy one was built in the later 1970s as a special here I think - I notice Tommy's are from 1972 and 1977 respectively.
Tommy, it's always nice to see more of your collection, do you have one of those silvers 652s or Constellations?
Si
