Unit 355, M109, availability date 1975-1995
The iraqis did not aquire M109 in 1975.No such delivery is listed anywhere that I could find. They did however capture some M109A1 during the iran iraq war.

While, as I noted previously, the iraqis had little use for iranian tanks the captured APCs and SPAs were quickly put in service.
Here is an unfortunate iraqi M109A1.
