Help in identifying maker and age

Ive been told the original hallmark has been over stamped for export purposes. Even with the overstamped hallmark I still can not find any info of its history. Any ideas? Thanks in advance the hallmark reads JnBros.

 

The hallmark is a standard Birmingham one for 1892. If it were exported then over stamped you would see the stamp of whichever authority imported it, so I don't think that is the case here. I think the makers mark was perhaps mis-struck then it was done again slightly mis-registered. I don't recognise the maker though, sorry.

 

I agree. Here's the "s" date letter list for Birmingham.

Needs a cleaning, big time.

 

Thirded. It's a fob.

 

Glad to see you got your first post done @Mraduck!
