Body construction: The body consists of a seamless steel tube over which are fitted rings cut from cast-steel pipe. Cast-steel nose and base piece thread into this center tube.

Tail construction: Four rectangular sheet-steel vanes are welded to a length of one-inch cast-iron pipe that screws into the base filling plug.
