On the ink reserovar it is written SCHMIDT, and since they also make nibs, I would say these are also made by them. I have contact them some time ago for pen parts, but did not get any response. But they make a lot of different types of nibs a seen on their web site

While we are on the subject, and that I am quite an amateur on nibs area, would you be so kind to tell me this:
1. on the internet I have found that there are 2 types of nibs - steel and gold.
What type of the nibs are on the pen kits purchased at CSUSA (perhaps some 3rd type of material) ? Are the golden the best ?
Pretty well all stock nibs are steel and the color is just for show.
2. if I would like to offer the customers better nibs as on original CSUSA kit - is that possbile ? Can I change just the nib ? And where and what type of nib should I buy ?
Yes, you can change just the nib. Lou, member DCBluesman sells nibs. His steel semi-flex nibs are very reasonable and write far better than most stock nibs. He does offer 14k nibs, if you and your customer desire to go that route.
3. do you usualy try the fountain pen (nib) before passing it to the customer ?
If you do try the nib, it should be dipped ONLY and then thoroughly cleaned. A true fountain pen aficionado does not want anyone else to use the nib.
Thank you in advance for possbile answer. Since I sell more or less only fountain pens (roolerball seems 2nd grade pen to the people, I guess), I must learn the basics.
As noted, Lou's Behind the nib articles are informative and the Internet is loaded with good information on the subject of fountain pens.
Thanks, George
