Mike those were made before 1936.

From the above table the buff box of 9mm was made on 13 September 1932 and the yellow .318 on 16 February 1933.

They would certainly be corrosive rounds.

The circular “Non Fouling bullet” stamp on one of your boxes indicates the use of gilding metal instead of nickel for the bullet jacket. It does NOT mean Non-Corrosive.
