Greetings.
The pictures should tell the story. It has the smaller mounting hole that won't fit on an 8 mm stand. It's thin but it lays flat on a counter top (last photo), so it's not warped. Several flea bites/nicks on the edge in various places, but no cracks and none of the flea bites are very deep at all. It weighs 238 grams. It is just shy of 10", about 9 7/8". Center hole is round and true with no keyholing.
$60 plus shipping.
