Stylistic I would put the vase in the last quarter of the 19th century. From what I read, the hand was used extensively on nickel-silver plated pieces in the UK ("old Sheffield"). Not sure though.
I am new at silver hallmarks and was wondering if anyone knew anything about this mark. It looks like a tower, a hand, and a capital D. Thanks in advance, Chris http://www.terribletrio.com/redsox/sm3.jpg http://www.terribletrio.com/redsox/sm2.jpg http://www.terribletrio.com/redsox/sm1.jpg
