Manoj Deshmukh is the person behind Fosfor who actually handcrafts the pens on his manual lathe.
Manoj has gone from strength to strength. He started off as a hobbyist pen turner showing his work on FPN and today has developed expertise with which he can realise your pen ideas with finesse. You can see a lot of his early work here.
I repair a lot of pens including piston pens. A modular piston filled pen which can be fully taken apart without needing any tools is a sure plus. Additionally if the whole piston filler is replaceable as a component like say an ink converter is, the advantages are obvious.
In middle of 2017, I approached Manoj with some sketches involving the design of a pen based around the Schmidt KFH450 piston unit. The design features were tool less disassembly, no gluing of any pen part to the piston unit, differential piston knob. Meaning the piston knob will screw out as the piston is extended. The last part is very conventional today thanks to Pelikan and later MB but somewhat tricky to do with the KFH450. Since it involved some machining techniques I had a brief initial discussion with Manoj and he assigned me a slot no on his work queue.
My slot finally became live this month. After a long wait of nearly 22months.
I received the pen and I am happy to state that Manoj has exceeded all my expectations. He has taken the idea and created a pen which is uniquely his. I am very happy with the work. Well done Manoj and thank you.
Here are some pics:
The functional Fosfor packing. Practical and compact.
The pen is made of NYH Red Black Cumberland ebonite with solid silver fittings.

Showing the differential action. Piston seal is visible in the ink window when the piston knob is screwed out.
The pen disassembled showing the KFH450 piston unit. In case of any serious maintenance requirement in future, the entire piston unit can be changed out very inexpensively.
Notice the hand knurling done by Manoj on the knob.
Size compared to a Pelikan M1000:
Thanks to Manojs mastery over the lathe, he is able to cut Multi start threads and the cap takes just 1-3/4 turns to cap-uncap.
The KFH450 uses the Schmidt FH452 nib units which are quite commonly available with a choice of nib widths.
Manoj charged me a very reasonable amount despite the amount of work involved.
I hope this brief write up is useful for others considering a custom job.
