22 Rimfire, Headstamp ID

Top may be Czech or Russian ?? made by WHO??
Bottom may be High Score ?? made by WHO???

Any help appreciated, Terry.

I believe the top to image is Cartuchos Deportivos de Mexico SA
Tepoztlan, Cuernavaca, Mexico or Poongsan Corporation Seoul, South Korea for PMC.

The second image is Hy-Score by IMI Australia LTD, Australia or Imperial Chemical Industries of Australia.

The top one is PMC.

Thank you Gentlemen , Terry.
I had this information and deleted some lines when putting pictures of headstamps into my data base. And know have a back up disc!
