Most likely a Dish Holder of some sort, would of originally had a glass insert. For sure if it is silverplate you will want to get a polish to clean it. The scroll work will be really hard and almost impossible to throughly clean. It may just be that this item has a century of tarnish on it, and not actually cooked on. If you take on the task of cleaning the scroll work on it, you will want to spend some time cleaning it throughly, half cleaned scroll work will not me that good looking. As a warning do not use the Silver cleaning dip, this can ruin silverplate and Antique items. Is it possible to get pics of the hallmark, this might lead to a better conclusion as to maker and date.
