Thanks for posting the pictures Cory. I found in a folder dated 2010, and I can not remember as to how or who send to me . I really like the second one shows the size of the trucks.
In August 1970 International Harvester company acquired 100% of Pacific Truck and Trailer. Pacific was a highly successful operation prior to acquisition. Throughout the 1970's production ran at around 30 units per month, with many trucks destined for operations overseas and the 500th truck built by Pacific left the plant in 1971. As a heavy-duty manufacturer Pacific was in a unique situation. Pacific was a small company which allowed it to adjust its product to comply with specific job requirements. In August 1971 Pacific received an invitation to tender four trucks from IH of South Africa. The South African Railway was to be the end user of these trucks. And were to be used in hauling 150 ton to 370 ton loads. Most of the loads were for Thermal Power Plants, although they could be used to haul any heavy loads. These trucks were 600 hp each. Pacific received the tender and advised International that it would not submit a quotation until Pacific's manager of sales engineering and product development Mr. Gwynn Jenkins had consulted with the final user. Mr. Jenkins went to South Africa September 1971. In the first week of October Pacific submitted a bid for a Model P-12 truck that had never been built. May 1972 Pacific was informed that it was the successful bidder. August 1, 1972 final layout and shop drawings were completed. November 22, 1972 all four units were shipped by ship to Johannesburg South Africa. Amazingly this full sequence of events from receipt of order to full service had taken only 12 months. In the 1970's 18 of these trucks were built, 5 of these trucks were built called Ultra with 800 hp, powered by a Cummins V-12-1710 rated at 800 hp. These trucks had huge radiators since they operated where temperatures would be 40 degrees C. From the top of the cab to ground was 13 ft. In 1973 the P-12 became a regular production truck.
