Harrison Electroplate?

According to the website, silvercollection.it, this electroplate item was made by John Harrison and Sons of Sheffield, between 1843 and 1865. Can you give me an idea of what it is worth? Is it a coffeepot or a teapot?

It’s a coffee pot. I would suggest a value of £30 - £50. However to get that you must polish it and show that there is no plate loss.
