Serveta Jet 200 frame numbers

Hi,
I don't know if I am in the good section.
I would like to know if some of you have heard of a particularity in the frame numbers of the earliest Serveta Jet 200 (those with the stripes stickers).
Is it possible that the prefix is Li150 on the first ones?
Thanks.
JB
