Hello, I am looking for information about this Tree of Life meat serving platter. Is this silverplate? Sterling silver? Who made this? There is crown, a shield with two lions/ugly dogs, and what looks like the letter C and a backwards letter P on top of more squiggles. I hope I have successfully linked to Imgur for the two pictures. Thank you for any leads.

You normally need to embed your photos to get answers. We do have easily found information on that mark, but we need that photo posted so we don't get our hands slapped by management for jumping the gun.

Hello, I've read the instructions for How to embed a photo at least 10 times. Still trying but can't seem to get it right. Do I copy and past into the URL tab?
