I found this seller on ebay. His handle is corncobpipes They make stems for cobs. Just like Walker Briar Works Forever stems, but a bit cheaper. I haven't bought one , so I can't comment on the quality. There are one or two I have my eye on. I plan on buying stem or two from him, and a forever stem from Walker Briar Works. This guy doesn't make stems for the unfiltered cobs, so I'm gonna get a stem for my MM Pony from Walker Briar works.
