Vintage Book Chain necklace

This isn’t mine but I saw it in a charity shop and it looked interesting. I didn’t have time to wait in the queue to see it properly but do you think it is anything of interest?
The white beads didn’t look quite right for plastic but I was fighting the reflection of the glass hence the poor photos. The clasp looks like a hook.
Does the chain date it? Worth going back for a proper look?
Thanks for looking

 

It's not quite what I would call a book chain. It is closer to a belcher chain. Definitely an older piece, presumably brass. Can't tell what the white beads are.

 

I've seen similar links on 1970s necklaces. I think I even had one in the 70s, but with a different pendant.

 

Thankyou, I’ll see what I can find with that search term.

Could be. It wasn’t screaming ‘buy me’ but I thought it was interesting as I’ve not seen that chain before.

 

A belcher chain is a regular chain with round links. Very simple, but one of my favourite chain types. It is seen a lot on historic portraits, when you see people wearing those heavy chains. Renaissance period, etc.

 

Looks like 'rolo chain' also brings up this sort of chain.

 

Yes, it is the same type.

 

It's nice, but I wouldn't make a special trip.

 

It doesn't jingle my bells either.

 

My senses told me not to wait in the queue so glad to hear you think I made the right decision.
I find chains quite interesting though and as AJ said, sometimes they are recognisable from a certain period or revival. If it’s still there next time I go back I may ask to look at it just to get hands on.
Thanks all
