I can't figure out the markings on this. I'm think it's Henry Wilkinson, and I assume it's sterling, but I'm not sure. I hope the photo is clear enough to read, though I can try taking more pix if that would help.
Thanks for the quick response. Checking my Jackson's Hallmarks guide, I can see the style of letters is that used in the London cycle XIX (1836 to 56) for date letters. I do know Wilkinson did both sterling and plate, but I wonder if the font of the letters means this was made in London rather than Sheffield.
Your marks are EPNS for Electro Plated Nickel Silver. The spoon is silverplated over a metal alloy containing no silver. The style of the letters is just a generic Old English type, having nothing to do with the date or town of manufacture.
