I have read of 20 lb and 25 lb Cooper Bombs. Can someone confirm that these were two bombs of different type or if they were one and the same, one being wrongly described regarding its weight?

It may be 20 lb is the explosive weight, and 25 lb is the total weight including the casing. I can't find  a reference to confirm this at the moment.

Quote 'By July 1917 the veteran all-purpose 20lb Hales bomb was supplanted by the more robust and efficient 25lb Cooper bomb, later to be classified as a 20lb bomb. [Bombs Gone by MacBean & Hogben, Patrick Stephens 1990, p33]
HE Cooper bomb Mk I— Weight of case 20lb, explosives 4lb =total weight 24lb
Explosive substance: Amatol 80/20 (if filled Amatol 40/60 weight of charge 4lb 9oz)
Size: 24.4in x 5.12in maximum diameter

Thanks for this, Colin.
 
I've also found some useful information on The Aerodrome forum at
See post No.3, which also includes images of two pages of a Jan 1918 Air Ministry document setting out specifications.

Like Eric Morecambe, I was playing all the right words, but not necessarily in the right order   Smile
