Yes, they did make a roller ball to match. I purchased one at the LA pen show
in 2001. I can't remember who I purchased it from. They only had one example,
which they let me have for 50 dollars--quite a bit less than the $200 retail
price.

I had been looking for the rollerball for nearly a year before I quite
accidentally stumbled on it at the pen show. I have no suggestions where you
might look today.
