Mushroom selling Chrome Knobs Cabinet Drawer Pull Set of 6 Vintage 1 1/2inch Hollow Concave UFO

This listing is for a Set of 6 Vintage 1 1/2inch Hollow Concave UFO Mushroom Chrome Knobs Cabinet Drawer Pull . These pulls are a Bright Chrome color that measure 1 1/2 inches across the face and each shows some light ware but mostly only to the backs, though one does have some scratches to the face. Screws needed for install are included. The stems have a flared base. 2 of these stems are slightly smaller then on the other 4 pulls but these are otherwise identical. No maker marks that I can selling find. See pics.
