Featured EAPG Plate with satin finish - Late 1880's?

So this is supposed to be a late 1880's EAPG plate that is signed. There appears to be a warrior killing a lion in the middle with a satin finish. The outside has clear glass petals with alternating designs. The signature looks like "P J Jacoe . .". It is 11 1/4 inches in diameter. It looks like it was used as there are scratches across the surface. Is this a real EAPG plate? Any help appreciated.

 

As usual, speed of light! I am thrilled to have a piece of EAPG! It is striking too! Thank you.

 

EAPGS has a bit of info on 403 Ware

Very interesting information. It puts the plate slightly earlier than I thought. It also gives an idea what a service would include. Thank you. I'm glad I got the one with the warrior rather than an obscure politician

 

George Nesmith would have loved seeing that. He was a great collector of Gillinder.

 

I didn't know he was a collector of Gillinder. So sad he's no longer with us to enjoy and participate in this discussion. I liked him very much. Thanks for sharing this.
