Walker, Roman fibula, coins and mount

On 1st April 1863 it was reported that "The Rev. J. Bewick, of Shields, has presented a few Roman bronze objects lately discovered in debris of the Roman wall at Walker, viz., a fibula of the usual form, 4 coins of the higher empire, and a nondescript crown-like article which had probably been sewn on leather. The Society of Antiquaries has purchased a fine quern from the same locality". It has been suggested that the 'non descript crown-like object' refers to a peltate mount donated to the Society of Antiquaries probably in 1863. This is the most complete example of a mount decorated with three-dimensional figures of reclining tigers found in Britain.
