1. Have you asked also on the Ericson site?
2. I had a new pulpit fabricated by a local shop. They did a horrible job and used substandard metal that rusted right away. When some bozo hit me at anchor a few years later, I had Rail Masters do the work, superb.
3. You don't need a pattern. If the folks doing the work can't figure it out, you're in the wrong place.
4. If you have photos, even a brochure, that would help.
Good luck.
