To answer the OP, there were three different 351C oil pans. One was a simple open bucket. #2 was the same pan with a sheet metal baffle down in the lowest point to serve as a "baffle" around the pump pickup screen. #3 was the same pan again with the sump baffle plus a rudimentary scraper on the sloping part of the upper pan. This is the so-called 'Boss" pan and is what shown in the photo. Some are date-stamped on the outside of the pan bottom.
All three stock pans are dangerously inadequate on a Pantera, because of its cornering capabilities even with stock tires. Quite a few owners have lost engines with full stock pans due to oil moving away from the pump pickup on acceleration or cornering. If you drive the car as it was meant to be, you WILL spin a bearing and/or launch a rod. An Aviaid pan, or one from Armando (who worked for Aviaid, then started his own shop) is cheap insurance compared to replacing a block.
