DescriptionThese two nearly identical devices, one pictured with one side up, the other with the same side down, could be S3-type transducers. Each device is shaped somewhat like a lidded pot with a pan-handle: a stout cylinder, rounded out so as to be thicker on one side than on another, the metal handle emerging from nearly the thickest part. The lid is securely fastened on, bolted down in about twenty places around its circumference. Along the middle of the cylinder is a rim. Opposite the pan-handle part of the cylinder is a tiny hole. Each has a cord extending from the end of the pan-handle. Both cylinders are metal and rusted, although one is more greenish than the other.
