The Clam is a small time bomb with a magnetic base, which enables it to be attached instantly to any flat iron or steel surface, such as engine blocks, railroad tracks, steel plate, etc.
The body is a black plastic box with rounded corners, measuring 5 3/4 in. x 2 3/4 in. x 1 1/2 in. At each end of the box is a magnet compartment, in which the two magnets are loosely mounted so that they can grip an uneven surface. The center compartment of the box contains about 8 oz. of the HE filler, usually Tetryl/TNT 45/55. The box is closed by a flat lid held in place with four screws.
A standard L Delay Switch No. 9 Mk I, with a Detonator No. 27 attached, serves as the delay initiator. It slips into a groove in the top part of the body and is held in place by a small clip.
No information about functioning.
Nothing else to see.
