Width of links approx 1 centimetre. (Bearing in mind the links are curved, not flat and hard to measure). This is an old chain and there are obviously marks commensurate with age and wear; the hallmark on the oval link is worn and hard to read but I have photographed it as best I can. These kinds of chains are now getting rarer and it is a lovely piece despite (or because of) its age.
The value will only increase in years to come. Please examine all images carefully. I do not know what the hallmark on the padlock means, or exactly what year this bracelet was made. All weights and measurements are approximate.
