There is a way to date a Fuji GW690 III by the serial number ?

I have seen a blog post dating one by serial number but there wasn't explained how to do it.

In Photo Thinking: Fuji GSW690III Professional – The Texas Leica, the author claims to date the camera by serial number, but doesn't explain how to do so.

My camera, based on serial number, does indicate it is a mid-nineties model...

Is there a way to date the Fuji GW690 III by serial number? If so, how?
