Help on mysterious Ti frame

[kiwideturin]

A little help of the RB community will be much appreciated
A potential buyer of my (too tall for me ) frame is pretty sure that it's not i believe it is (a 98/99 french Lapierre)
Any idea on what it could be? Syntax of the serial number analog to another brand? Details same as on another frame? ....

Closer pics here and there

I am afraid that I can't identify your frame but I do have a mystery frame that is similar and I would be interested in anything that you find out.
The frame numbers are very similar.
