Arch Motors chassis ID numbers

[davidball]

Does anyone know if Arch Motors stamped an ID on their chassis other than the VIN number?

[mickrick]

Yes, under the rollbar mount. AM and the jig number.

Thanks.

It normally has the year of manufacture after the AM stamp and the chassis number below that as well.

Arch only stamp the Jig number.

Caterham stamp the chassis number.
