So, I was trying to find an actual vintage version of the Conklin Crescent Filler (aka, the "profanity saver," according to Samuel Clemens) pen that was restored and in decent condition... But, I only found two, and they were well above where I wanted to be price-wise. So, I settled for the reproduction instead.
I have to say, even though it has a JoWo Omniflex Stainless Steel nib, it's a good writer. In fact, so good, that when it started acting up on me the other day it took me a few minutes before I realized the issue was that it was actually out of ink... I had actually written enough with it to go through a complete fill.
He did a whole video about it a month ago: The 3D Printed Fountain Pen Project Has Begun!.
I just emailed him a table from my ink collection which I put together per-unit pricing. There were a couple of surprising things I found. Given his recent video about inks I thought he might find it interesting.
