Just wanting to know if the circled objects in the pictures are PMD or error/varieties? The "O" I have circled I first saw when looking at it with the microscope. The square area looks to me like denticles. I would like some help with what to classify them as. Thanks.
I don't have the VAM book , so this is just opinion . But it looks like PM damage . Looks to have been hit with something . I'd wait for a VAM expert 1st though .
