Jordan 199 - Chassis numbers

[superflyte]

Hi all.

I am looking for information on the Jordan 199 series of chassis built for the 1999 season.

Does anyone have information on how many cars / chassis were manufactured? The Giorgio Piola book for that season suggests 6 were built, but I have seen a chassis build plate listing that car as chassis 010.

Hoping the knowledge pool here can help!

Thanks
