Gazelle? Does anyone know anything about them?

Mr cheese, I've just acquired a gazelle cyclocross frame and fork with the serial number:

4005737

Any idea of the date of manufacture from this number?

Thanks!

I guess the frame was build between 1995 and 1999, compared to the other serial numbers:
