yup. It’s a meat juice press.
It is made of cast iron and the inside of the press part is tinned.
I was able to find reference in a 19th century medical book about the use of a meat juice press to extract the juice from a 2 ounce piece of beef.
“The liquid obtained contains all the nourishing qualities of the flesh, and none of the indigestible structure, and it is much more palatable than ordinary soup or beef tea, and is decidedly more nutritious.” -1887
I guess if your teeth were bad and there were no vitamixes you’d have to get your meat somehow.
I’ll have to give it a try and see what I can manage to get out of a piece of meat.
