I got this material, named “hirta,” from the Turners Workshop. I thought the ruddy browns would be complimented by some red-mottled ebonite finials, and section. So…there you go. 12mm 3x barrel, 9mm blind cap which removes for access to the converter. The clip was a black-enameled item from Beaufort Ink…but I (deliberately) buffed it down to brass for this pen.
