After World War II synthetic fur, a deep-pile fabric closely resembling fur, became popular. George W. Borg was among the first to adapt circular knitting machines to make a pile fabric from synthetic fibers.I ran across a unique passive filter. Wonder if anyone has seen or heard of one. It is Military surplus. It is called Radio Filter FL-30. Made by The George W. Borg Corp. It appears to consist of potted torroids. It is about a 2 1/2 inch cube with a large 3 position switch on top.
