We have started to design Fountain pen kits as well as the ball point kits.
We also have the 11.5mm upper tube and 10mmlower tube sets. These are the Baron/Navigator Sedona sized Fountain pens. FP7000 and FP8000 series (not shown)
We also have Front sections for Bock and Mesiter Nib feed assemblies.
FP1000, FP2000, FP3000.
The 2000 and 3000 upper assemblies will interchange as the cap threads are
12 x.75mm for both. Different finials are being developed for all sizes as well as post able and non post able lower tube caps.
Upper tubes can be as large as 9/16 brass tubing. WE also have assemblies/parts that will fit/replace most of the current popular fountain pen kits.
We csn provide custom center bands and clips as needed for our clientèle.
