No problem! I'm working on one or two projects at once, so not taking my time up at all!
I see one of the little dents you mentioned, which are not going to affect value that much on a piece like this. I would not worry about them.
What you have is actually called a tea kettle and warming stand, for providing the boiling water for pouring into the teapot. It was the crowning glory of the tea tackle in all the best drawing rooms of the day. The burner was filled with spirit alcohol and kept the water in the kettle "screeching hot" as William Makepeace Thackeray described the necessary temperature for the making of proper tea in his 1869 "The Irish Sketch Book".
It was made by the very reputable maker, Reed & Barton, of Taunton, MA. in an Art Nouveau pattern that dates it to around 1890 - 1910.
As for value, this similar one
sold on line for $152. This was some time ago and is a little on the low side for today's prices. I would give yours an auction/on line value in the range of $200 - $300.
It therefore has a full retail or replacement value of $600 which is what you should insure it for.
I hope this is helpful.
