OK, it's .65 of a millimetre deep at it's deepest point & thats right near the rim.
When i first looked at it i thought the rough texture looked like struck through grease/oil but i have never seen grease/oil fill with jagged edges like this has ,so discounted grease/oil fill.
Oh & scales battery is flat so will have to get the weight tomorrow.
