Thank you.

351-92 = China - corrosive

31-64 = China - corrosive

13-88 = Cuba - corrosive

#3 is more likely to be South African mfg and NONcorrosive.

Any way to tell the difference between Cuban and South American?

Well the ammunition has a lead bullet and I think a brass case which sounds South African but most all of it around is 88 and who knows what the bullet and case are of the Cuban. It might be Cuban sold as "South African" because Cuban ammunition isn't allowed to be imported.
