Let me start off by saying that I know that the general advice is that a sporran all-leather strap is better than a chain. For some occasions, though I think chains lend something extra. I am particularly attracted to vintage chains that have a nice patina. I am wondering if there are any qualities people with a discerning eye would identify as indicating quality. For example, what type of links; what kind of clips; are there differences in the buckles; are there material considerations beyond the obvious sterling silver)?

Cheers,
