I spotted a post elsewhere that had a picture of a Neponset with a Zebra G nib, so I immediately got to work. Sadly, the Neponset ebonite feed curves downwards quite significantly. I recall this issue with the other one I have that I put a Goulet nib into. To do that I had to remove the Neponset feed and replace it with an Ahab feed and now it works perfectly and beautifully wet. The problem is I cannot for the life of me work out how the person managed to get the Zebra G nib to match the Neponset feed - mine are so far apart that you could drive a bus through the gap. They claim to have heat set the nib and feed, but I can't see how that would be possible without damaging both the feed and the nib....am I missing something?
Presumably I could stick a zebra g into an Ahab if all else fails?
