Mystery Mark - 830s + Bowtie Oval?

[natNYC]

I've been searching for this, but can't find a similar hallmark.

It is a bud vase and two candle sticks. The tops are solid, but the bottoms are weighted. They have a nice mid century look to them.

Each piece is marked on the bottom rim (above the thatched design)
, the bud vase is "830" oblong oval and B
The candlesticks are marked 830S - oblong oval and 434

Thank you for your help!
