Mathmos Galaxy issue

Hi,

I approached Mathmos about the color disc of a Galaxy, their answer was "no help".

So I decided to have a glass round cut and apply colors segments. Opening the lamp made me discover that the motor moving the disc is dead.

There's nothing on it besides 48/73 on a face and "Brevete SGDG Made in France" on the other.

Any idea about finding one for replacement ?
