Thank you for submitting your item for appraisal. This appears to be some kind of novelty grinder combined with a table bell. The material is silver plated Britannia metal. Thanks to the date of the patent mentioned on the bell, the novelty item can be dated to after 1863. Unfortunately the online search in the national Archives yielded no result, an there is no diamond Registration mark.
The estimate is based on other novelty table bells offered or sold.
