Unit on left is a speckled reddish-mahogany color, lighter than photo shows. On the dome is incuse marked "C/NZI/49. On right, is a salt kind of glazed dude, ... kinda rough and sandy surface. This one looks a little more yellow in person than the photo shows. On the dome is incused "G.P:O." with a second dot between P and O as shown. I am confident this makes it one of a kind and worth thousands, right ? You can have either for $15 + postage.
