£150-200

Condition:
Unable to confirm 100% if the initials are AR as the mark is very rubbed. Interior of lid and base is very tarnished. Small dent to top right rear rim of the lid. Minor surface scratches in places. No holes or splits. Lid does not quite close flush with the base towards the left side. The piece tests as silver but has no hallmark.
