Unknown hallmark on neo classical candlesticks

This is my first post so I ask your tolerance up front if I have not posted properly. I inherited this pair of neo classical candlesticks and know nothing about them. They stand 9" tall. The only hallmark I can find is inside the bowl under the candle sleeve protector. There is the number 11085 (perhaps a pattern number?) and the mark is a triangle with a circle inside. Can anyone identify this mark? Thanks in advance.
