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? Errol

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.

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
