Here’s an interesting engine plate from A.G. Mumford of Colchester England. I think it’s 1880s-1890s?  Measures roughly 8.75″ across. About 1/8″ thick. Heavy. Interesting letter engraving style. Has knicks, gouges, scrapes, abrasion of all kinds. See photos. Was polished at one time. Has patina. Nice old plate and it would display well.
