chassis marking

[analog_me]

Hi all do you know what the number on the chassis next to where the roll bar bolts on stands for?
See below

AM is Arch Motors, J2 is "Jig 2", they have 2 jigs on which they made the chassis.

Can't help with the rest.

AM = Arch Motors
99 = year of manufacture
J2 = Jig 2 (I don't think they have used Jig 1 in years)
4593 = frame number, i.e. the serial number of the chassis

I think!

Great thank you gentlemen
My caterham Chassis number plate located inside the engine bay is different.
I remember i was once told by caterham Arch Motors do not use the carterham chassis number so i guess they must have their own.

Congratulations! You have an Arch chassis

Arch make the chassis, so they give it a number for their records.

Caterham are the ones that dish out the chassis numbers, so the two are unrelated.
