Am trying to correctly identify this Mexican silver dish I inherited. It appears to have three of the four marks on the .925-1000 website's photo of 19th century Mexico marks. Here are the photos:

If anyone can provide information on what these marks mean and/or ideas to purity, I would appreciate it.
Many thanks!
