The paykan was an arrows Hillman Hunter from 1967 which by then Chrysler were taking over.
The Supersnipe pick ups were built on the chasis of the MK111 and MK1V models, the former a 4 litre straight 6 side valve the latter a 4 litre straight 6 ovh. They lacked the luxury of the saloon as there was no carpet. I built one in 2010, it was in the national day parade in Qatar, they had a historic section of vehicles that had worked in the oil fields of Qatar. In total I shipped 5 Humbers. The first recorded vehicle to work in Qatar was a 1929 Morris one ton truck. I had the task of finding one and persuading the owner to sell. Once I figure how to post photos I will.
