Victorian double Albert pocket watch chain, adjustable double albert

An adjustable double Albert pocket watch chain in good condition. The material is magnetic and the colour is somewhere between brass and copper and it may have once been gold plated. It is not marked apart from on a little tab 'EO' and something illegible. It has been well-loved and is showing wear consistent with its age. The central loop goes onto a button or button hole. The spring to the clasp is stiff but working fairly strongly. The little eyelets underneath have space for a fob. The chain can move freely through the middle loop. The clips at the end both work well – one has a little bit of space on it's lip so it's advised not to put anything too slim / narrow on this side. Its 18-1/4 inches or 46.5 cm long in total.
