Please help. I need a silver hallmark ID

Hi there. I need an ID on the hallmarks on my grandad’s silver cigarette case which he was awarded for saving 2 mens’ lives. I’d like to know a bit more about it. Thanks in advance!

That is a Chester hallmark for 1929/30. The maker’s mark, P&B, is not known to me. P&B were probably based in Birmingham as I have previously seen the mark with a 1929 Birmingham hallmark; many Birmingham silversmiths used the Chester Assay Office when the Birmingham office got too busy.

Thanks so much for your help.
