1969 Cowl Partial VIN

[john jay 69Z]

Hi all, would anyone know What H 28 1 stamp in the centre of Cowl area represents, I was going through my photos that I had taken during the restoration documenting my hidden VIN numbers. I was thinking it might be a body date stamp, 28th August, seeing that my car is a 3rd week of September 1969 built but have not found anything yet to back my theory up.

Any thoughts,
John Jay 69Z

Hi Joe,

Good to hear from you,
I think I didn't explain my question properly, in the cowl area where the partial VIN numbers are stamped there is also a H281 stamped to the right side of the vin stamping so almost the centre position of the cowl. I haven't come across so far of anyone mentioning this or in any literature, is this a standard body stamp on all Camaros or is it a date stamp for each individual body shell. I was hoping someone could shed some light on this.
Thanks again,
John
