Cowl Tag Decode

[mssl72]

Thanks Jeff. I had to throw this out to the masses. Those numbers at the top of the tag had me going "huh?". I haven't been able to find anybody that knows what they mean. Just so you know this tag is from a '68 L72 Biscayne. One my buddies owns it. It's currently going through a body-off and we're trying to figure things out. He does have the Proteco-plate, but there isn't anything on it to give us any clues about the other numbers. Maybe you're right about the die being busted.

Has anybody else seen a tag like this or have any ideas??
