Pair of Copper and Wood Base Arts and Crafts? Candlestick Holders

I have this impressive pair of hand-hammered copper ARTS & CRAFTS CANDLESTICK HOLDERS made of two curled, flat copper bands riveted together in the center and then rivet-mounted to the top of the large, thick flat copper base (10" long x 3" wide). Each of the flat textured copper 'curls' supports a 2-inch high x 1 3/8-inch diameter flared bobeche candle holder which is soldered to the piece.

The entire copper candelabra fixture stands approximately 6 " high and is riveted at the four corners to a 12" long x 5" wide x 3/4" high walnut wood base. One base is bare on the bottom and the other still has brown felt. I have found no marks on these. Like many of the things I post, these were purchased at auction about 30 years ago. I am hoping to determine if these are actual Arts and Crafts era candlestick holders or if they were produced a bit later than that period. Any information would be most appreciated.
