This is a C.M. Hall Co Solar model S lantern.  It is in good shape for its age.  It features a red and green lens on it side.  There is slight cracking on the green side as shown in the pictures.  It appears to be on the surface and not all the way through as the lens is still secure and not loose in its mount.  The main lens is clear and clean.  It has a few dents and scraps but nothing that takes away from the display of this piece.  Take a look at the pictures and feel free to ask any questions.
