Can you name how many marques the Arrows were sold under?
I'm no expert, but I believe that in the UK, they were sold as:
- Hillman (Minx and Hunter, 1966-1976);
- Singer (Gazelle and Vogue, 1966-1970);
- Sunbeam (Vogue, 1970-1971);
- Humber (Sceptre, 1967-1976) and then
- Chrysler (Hunter, 1976-1979).
In mainland Europe and North America, the Sunbeam marque was used on most Arrows, because this was the best-known Rootes marque overseas. A mixture of model names and trim levels were used in different countries under the Sunbeam name (Minx, Hunter, Vogue, Arrow).
In Australia, the car was sold as:
- Hillman - HB Range (Arrow and Hunter, 1967-1968) - same as UK models (CKD kits)
- Hillman - HC Range (Hunter and Hunter Royal, 1968-1970) - some different features to UK models
- Hunter - HE Range [as a marque in its own right] (Royal, GT, Hustler, 1970-1972) - unique rear lights and other trim
In New Zealand, the car was sold as:
- Hillman (Hunter, 1967-1970)
- Singer (Vogue, 1967-1971)
- Hillman by Chrysler (1970-1979)
In South Africa, the car was sold as:
- Hillman (Hunter, Arrow, Vogue, 1968-1976) - using 1618cc Peugeot XC engine, from the 404
- Chrysler (Vogue 2000, 1976-1977) - using 1971cc Peugeot XN1 engine, from the 504
- Dodge (Husky pick-up, 1976-?) - unique pick-up body, using Rootes 1725cc engine
And, of course, the Paykan.
As far as I know, the Paykan utility pick-up (Bardo 1600i) used a different body to the South African version.
Hope this is some use as a starting point anyway!
