The sterling cap old style Paragon from Regina Martini came with an 18k medium nib that had much too wide a space between the tines. I prefer bit narrower nib so this pen was off for a "fix" to the flow and a bit narrower nib.
The sterling cap/body Optima from a fellow FPN'r came with a broad nib and I was fortunate to find a second, identical broad nib on Ebay. Although both nibs were "perfect" as broads, I already have a good selection of Pelikan broads so these two also went to Greg to result in a fine, like the Paragon, and a medium stub.
First, for those who haven't worked with Greg, he's a pleasure to work with. To say he's detail oriented is an understatement. He will make sure you know what you want before he goes to work, including his request to include writing samples with the pens you send. In my case there were things he wasn't sure he understood that resulted in a phone call to me prior to starting work. Then, after the work was complete he sent photos to demonstrate the finished product, including writing samples next to the writing samples I'd sent....even
I'll post the photos when I get some time in the next week.
The end result met all my expectations. The Paragon has perfect flow and the fine regrind was dead on to the writing sample I'd sent. The Optima now has a "split personality". The fine is perfect and identical in stroke width to the Paragon and the Pelikan fine sample I'd sent. It almost seems that the nib even retains that unique Aurora nib "feel" despite having been taken from a broad. The stub is truly a joy....smooth and forgiving but full of personality and variety in the vertical and horizontal strokes. This nib will likely stay on this pen most of the time. It started as a .9mm broad and ended up a stub between .89 mm and 1.0 mm depending on pressure.
In conclusion, my kudos to Greg both for his attention to detail, great communication and fast service. Although he advertises 2 to 4 week service, my 11 day turnaround kept me from having to look longingly at the empty slots in my pen box...especially for NEW pens!
