There are several models that have a pump directly under the barrel but non that I know of have a pump down the barrel. Some of the early Benjamins (1930 to 1940's had a pump directly under the barrel. Models like the 100, 110, 112,117, 122, 130 and 150 (there were several others) Later models had a swinging pump under the barrel.
