I've never done it, myself. But if you want some, I can probably dig up some Deer from the late '40s and early '50s at my grandfather's place. The jars now look like they are full of albino rats that were pickled in some kind of red solution.
Whatever they used in their canning process drew all of the color out of the meat. It's just a dirty tan/white color now, in a dark red liquid.
