This is a centerpiece made by William Hutton and Sons of Sheffield, England in silver plate (not sterling silver) in pattern 31209. The EP ( you said DP but I think it is EP) and A1 represent Electro Plate in A1 quality, a mark they used from 1864 to 1893. This piece has a current value of $400usdollars or 261GBP.

There were different versions over the years, yes, I would need to see the mark in a photo. Please add a photo of the piece and the marks so that I can re-evaluate for you. You can add pictures by using the ADD FILES button in the lower right of your screen.
The pictures did the trick. I did not realize the words CROSSED ARROWS were part of the mark on your piece, I though you were just referring to the symbol of crossed arrows in the middle (without the words was earlier). This is why photos are so important to add in the original query. The mark that I thought was EP is BP for Brittania Plate (same thing, just a later term). You are correct, this mark was used after 1901. I do not think it is a centerpiece now that I see it. This looks to be a wine bottle holder, something that Hutton did make in different versions over the years. Hard to tell by the scale of the piece-is it a size that a wine bottle would fit in the forked branch to hold the neck of the bottle? As a William Hutton and Sons wine bottle coaster, this piece has a value of $125USD.
