Not sure what the exact caliber this was listed as (inches, mm, or a gauge like English X-pound guns), either way it is about a 3" projectile. The round alone is 11" long, so the casing must have been just as large. Quite a nasty anti-personnel round, the 4th image describes how it functions after being fired. The brass fuse on the top sets the time (altitude) at which the round will go off, ideally at such time to spread the shrapnel over enemy trenches. It was used mostly during WWI and also saw some use in WWII, just to a much lesser degree.
Picked this up at a local pawn shop a while back. It was fairly rusty and dirty, but I think it cleaned up very well. I tried to keep the rich colors of the patina while removing enough oxidation to really make them look good.
The other rounds in the image are (from largest to smallest) a 1942 dated 20mm round, a .50 cal round, and the humble .22 short.
