WW1 shrapnel shell

[F0031]

Two WW1 projectiles. The first (pics 1-3) I can identify as an 18 pdr shrapnel shell; diameter 82mm (3.28in), length 235mm (9.25in). The second (pics 4-6) is identical except that it is 3/4 inch shorter and a bit of a mystery.

18pr shrapnel came in different lengths depending on the mk.no.
