The cob inserts were made for some time by The Missouri Meerschaum Company, manufacturer of corn cob pipes in Washington, MO. The box shown is their box. They made the inserts from the early 1970's until 1983. They are no longer available from that source but do appear on ebay at times
The top of the vaned bowl outer unscrews to enable easy replacement of the bowl insert. An inline filter can be used in the stem.
