Date code? Sometimes you'll find similar codes stamped or cast into other pieces. 13F2 could translate into 13 June 72 or 13 June, second shift, or something like that. The mark would have been stamped into the core after the core was filled. The reason you don't always see them, esp in castings is the nature of how it was done. I heard that often workers would just say "to heck with it" on busy days.
