Pair of Guide TiltRay 10" headlight lenses # 222399.  From the info I could find, these should fit 1929-1930 Oakland and Viking along with 1929-1931 Buick and Studebaker.   I can't guarantee that those are correct so please double check your application.  They are in pretty good used condition.  There are some scratches and a small chip in the face of one of them.

See the pictures.
