Vintage Italian art pottery bowl & candle holders, Raymor Italy Bitossi?

Marked Italy pottery candle holders and covered bowl set, mid-century modern vintage Bitossi? The oval candle holders are 5 1/2" long, and the bowl about 7" in diameter. There's pale colored friction tape on the bottom rim which looks like it's been there forever.

We saw a few tiny glaze chips (pin head sized flecks or smaller) but no other flaws, it's a good set with a great modernist design.
