John, you and I have had a long term conversation on this subject, but I just ran across this box in the collection and decided to post it see if others have anything to add.
The box below was unfortunately empty when I received it, but sure looks like it would date from the period of the R-P headstamps. The box code is Z1-IT which if it was a real Remington code would probably be 1983.
It seems pretty certain that CDM was making Remington ammunition in Mexico during the period of the R-P headstamp. I would be surprised if this box had other than a Remington headstamp in it. I suspect that the headstamp was
R-P - 9MM LUGER -
A Remington headstamp confirmed to come from the CDM factory is
Does anyone have either of these headstamps in the original boxes?
Can anyone confirm what cartridges came in the box pictured?
John makes an excellent arguement why this is probably not a Mexican made headstamp. I hope somebody had added information to give us more insight into the origin of the two headstamps pictured above.
