Dave700x, thank you very much for the link to 9d5. I've been looking at the vams when I get a chance and mine certainly looks like one of these. I will confess that in the photo by Mhomei of the obverse diagonal crack, I'm unable to see anything, so it's hard to be sure. Out of curiosity, how did you find this
VAM? If I didn't have your link, I wouldn't find it.
Thank you suipakpaikungfu, that's good to know.
Cheers and good collecting.
