I saw such baritones. It is seems to me only earlier Weltklang baritones have such variant - lacquered and nickel keywork. I saw with rolled tone holes. But I can not say nothing about sound.
I also saw similar model for vintage B&S tenors - lacquered and nickel keywork (usually B&S saxes to 1990 year were silver plates horhs). Bad sound.
