Mississippi Fred has a put up a small booklet written in Spanish on shechita and bedika published in London in 1733. (Most of English Jewry was then Sefardic.) The above illustration comes from that booklet. It shows an animal that has been cast to the ground. The shochet is about to slaughter the animal as his helper controls the animals head using a stick and chain. The animal's right hind leg is chained to the wall, and his left hind leg and left fore leg appear to be chained together. The pit in the right foreground seems to be for the drainage of blood. Both Rubashkin and Alle import meat from South America that is still killed through casting.
