Raymarine ST4000 MK2 Autopilot Gearbox info?

Hi all,
Well, my Raymarine ST4000 MK2 Autopilot gearbox has decided to quit - 3 of the nine plastic gears stripped.

Before parting with $$$ for a new gearbox (if I can find one), maybe somebody knows where I can get some replacement gears?

Raymarine would not have made the gearbox themselves, so does anyone have an idea who manufactured it?
The motor is a Mabuchi RS-555-SH but it looks like they didn't manufacture the gearbox.
Any info would be most welcome.

Btw, in my search I have turned up parts list, diagrams, etc of the ST4000 MK2 - pm me for a copy.

Here's hoping....
