Sorry, I know this has come up a few times. Looking for someone in the UK who could
repair make work my Visconti Rembrandt.
(I've posted about it elsewhere, but never been happy with it. I think it has one tine longer than the other so needs a bit of grinding and probably work on the feed / feed replacement. Tempted to get it ground to a stub as well.)
I've seen mention of Oxonian aka John Sorowka but can't find him searching FPN members. Also saw mention of PenPractice.com but doesn't seem to cater for repair or modern pens.
