Not exactly a family Bible!

Back to the question of scale - how big is this?
It is actually just 4.5 x 5.5 x 1 cm  (1¾ x 2¼ x ½ in) and has 686 pages.
The front is silver, with embossed cherubs, the rest of the cover is leather.
It belonged to my Grandmother, who I never met. The message inside, facing the cover reads 'C C Kemp from V Tudor on Xmas day 1904' 
On the inside of the cover my Grandmother wrote '2.8.1934 To Norah (my Mum) Why she gave it to my Mum particularly I don't know - Mum was one of six daughters - neither the oldest nor the youngest  - perhaps she had just expressed a wish to have it. 
The last inscription reads '17.4.1994 to Valerie' I remember her giving it to me - she said 'you'd better have this now, I'd hate for it to just get lost or thrown out when I'm gone'.
So, 112 years - passed from mother to daughter. Who do I pass it on to - having no children? I do have a niece and two great-nieces so I suppose it could be one of them.
