Default Strange(?)stamped C3 differential code

Hi.
This code is stamped on a differential case: OH 101 W 9 E 1. possibly a 78 or 79. ( no side axles and rear cover)
The "1s" around 101 and after E are heavy stamps compared to other stamping. I tried 0,zero or O, in oh and nothing comes up.
Any ideas. ???
Thanks.

Thank you.
The 1s are a heavy punch stamp and around "101" they are way below the "0", like. 0 ?
1 1
