I have JoWo #6 and Bock #6 nib units in stock as well as a variety of TWSBI pens in stock if there is a grind you'd like to try. I may also have some Kasama pens in stock. Please email me if you are interested in acquiring a pen with a grind on it from me.
Here is a link to the pens and nibs I have in stock:

If you decide you’d like to get a pen from me and you see it’s something I have in stock feel free to fill out the form on my website and then email me letting me know that you’ve submitted a form to purchase a pen from me. That way I’ll know to grab your request and add it to my order processing system.
