The original Cascamite, or at least the powdered stuff in a tin I
recall from the 1960s, was, as far as I'm aware casein glue. (Casein
being a protein by-product of milk, as I understand it.)

One of the WW2 twin engined
aircraft (can't remember it's name now) was made of wood using this
glue and always smelt of sour milk. #

Probably the de Havilland Mosquito.
