It is essentially in 3 sections: The base, the mechanism, and the sanitary tube. The base really is the bulk of the metal; a rabbit ear with a screw in it, bent at 90 degrees to hold coils. In the front there's a round hole to hold the sanitary tube. Some people think the base looks like the handle of a gun. The base houses the mechanism, which consists of two coils of wire wrapped around an iron core.
