I have a demi-sized Omas, that has decided that the piston isn't in the mood to move anymore... it's a modern (1990s?) pen and has had very little use, since the feed is a single channel version and it starves for ink after a paragraph or two, as well as being unable to sustain feed for flexed writing of more than a character or three.

I know that John Mottishaw could fix this in his sleep, but he isn't taking work on anything that wasn't purchased from Nibs.com Suggestions for an experienced Omas repairer within the US would be greatly appreciated!

Thanks!
