Silver 'barrel Link' Necklace 80cm Long

Looking for something out of the ordinary? This could be just the thing! In essence this necklace is unusual on several counts 1. it uses a very unusual, pretty and complex 'barrel link' throughout. 2. at 80cm's this is a necklace that harks back to the 60's and seventies; when long necklaces were all the rage. Marks indicate it was imported and marks are for London, 925 and probably 1975, and perhaps from Italy originally.
