Iraqi 14.5x114 Headstamp

I picked this case up over the weekend. I have interpreted the entries at 10 o’clock and 2 o’clock as “87” (Presumably a date) and “14.5”. What do the two characters at 6 o’clock mean?

Thanks for any info.

The bottom numbers are ‘03’.

And the “03” is the factory code.

Thanks for the replies. Is there any more information known about “Factory 03”?

I wish I had. So far it is suspected to be the plant at Jarmouk near Bagdad (maybe it is a suburb of Bagdad).
