I have an old-style (knurled grip) rOtring 600 that has a broken plastic feed sleeve. This sleeve has a flange on the front that holds the knurled grip onto the pen. This flange cracked off.
I returned the pen to rOtring for service, alas, they did not have replacement parts available. They returned the pen (along with a replacement 'newton' series pen, very nice of them) but I would really like to get this one working again. (Sentimental value, etc) I've 'hacked' a repair via some friction tape and other skullduggery but it would be really nice to get the right part and do it correctly.
Does anyone happen to have any 600 parts lying about? Nibs perchance?
