Historical information

Patented by William Mills and known as 'Mills Bombs', these were first used in WW1 and were used by the British Army until 1972. Three models were made - No. 5, No. 23 and No. 36. The latter two could be fired from a rifle (with suitable attachments). Note that the casing is grooved to assist fragmentation. These grenades had a time delay fuse of 7 seconds initially but later a 4 second fuse was introduced. Upon explosion, its lethal range was approx. 90m but on hard ground it could be double that. Over 75 million were produced.
