From the photo, it looks like they're teakwood, which also points to a high-end price point. They are definitely not maple, which was not a fashionable wood for Modernist designs - maple was for Early American, according to the taste of that era.

The correct shade for this time period is what's called a "drum" shade, meaning that the shade has nearly vertical sides. A linen or burlap shade would be spot on the money for the era. Pleated, belled or flared shades were very, very seldom seen at that time on new lamps - they were considered completely out of style.
