"The Jinhao 750 feed looks identical to the Jowo.  They appear interchangeable in the standard Jowo screw-in nib collar/sleeve.   A fellow on Ebay is selling nib, feed, and converter sets for the Jinhao 450.  I asked whether he could get these sleeves as well. I was thinking of retrofitting an Indian eyedropper and a couple old busted pens.  I'd suspect pen turners might be interested as well. "
