This model is of the Fun Ho! #26 Ford Thames Pickup in chrome and red.
This is likely to have been an early issue due to the chrome finish, issued between 1964 and 1966. During its lifetime 69,900 Thames Pickups were manufactured, in Chrome initially and later with a paint finish.
The scale is unknown but thought to be around 1:77. My reasoning is that the normal length for the Ford Thames was 155 inches (3.93 metres) and the model has a length of 2 inches (50mm) (155/2 = 1:77, 3.93/.05 = 1:78). [notwithstanding the fact we all know these models were not made to a precise scale but usually to fit a set box size].
