In researching this I've found that the actual display is a Futaba Vacuum Fluorescent Display Module 2 Lines/20 Characters -- With each character using 5 dots wide and 7 tall.
The Futaba part was M202SD01HA and/or 202SD01B
Here's a link to the actual manual of the actual part: http://docs-europe.electrocomponents.com/webdocs/0031/0900766b800319eb.pdf
Those of you who are more electronically inclined may be able to figure out a replacement for this display OR may be able to find an actual distributor of these displays. If you can make in progress on this, please email me through the email form on the ASK QUESTIONS page.
