The Edison Hudson is the only production line Edison that I own, my others are either custom or Signature Line pens.
The lovely thing about the production line pens is that it allows everyone the opportunity to own an Edison Pen at a price that will not break the bank, $150 with a steel nib or $275 with a gold nib.
I purchased the Hudson in Emerald from AndersonPens back in June. It is also available in black and ruby.
I purchased this pen with a stainless steel F nib, but have recently swapped it out for a stainless .7 CI nib. The Hudson used a cartridge/converter filling system but, as with most Edison pens, it is easily converted to an eyedropper, which is what I have done.
This material is so difficult to photograph and show you the true depth of the color and glow. In addition to AndersonPens, the prodution line is available at these other great retailers:
