7 look to be military "LUBE OIL MG" cans then there is one additional mystery can.  SEE PICTURES.

Rust and signs of age as seen in pictures. All are about the same size of 3 1/4" x 4 3/4" not including their spouts.  The mismatched can is a little larger.  All of the military cans have their top spouts and chains.  SEE PICTURES.

GET A GOOD DEAL BY BUYING ALL 8!  Sorry, I would rather not break up the set.
