This example is offered in wonderful condition and as it is empty weighs about 10 lbs. When used in training it was most likely filled with water or sand to make it 25lbs. It makes a fantastic memento of a biplane pilot's time at war and well preserved for the past 100 years. This particular example features intact fin assemblies, which all have their securing bolts, and an original nose cap, which still unscrews easily. It has been repainted entirely, with OD green on the body and blue on the front end, while the nose cap was painted orange. It also has the original spring loaded post on the tail, which may have been for arming the bomb. The bomb has fantastic patina and is sure to find a welcome home in any WWI aviation collection!

Aerial drop bombs are divided into classes according to the use for which they are intended. There are three general types, viz, high-capacity (demolition), fragmentation, and incendiary, all of which have been designed and equipped to meet the requirements abroad. Changes are constantly being made in details, such as the method of suspension, to make possible the use of the bombs in new release mechanisms and planes.

High-capacity drop bombs, so called because of the large ratio of the weight of the explosive to the weight of the casing, are used for general demolition purposes. The targets engaged include fortified positions, railroad terminals and lines, heavy structures of all kinds, supply depots, ammunition dumps, etc.

Fragmentation bombs are used against personnel, such as troops in the field or on the march, or wherever the protection afforded is slight. These bombs carry a relatively small charge of explosive in a heavy steel casing and depend for their effect on the fragmentation of this casing.

Incendiary bombs are used for incendiary purposes against ammunition dumps, aerodromes, grain fields, etc. There are two types, the scatter and the intensive. Dummy drop bombs were used for instructional purposes.
