For sale here is the inner lettered translucent glass face for the large Hammond Lighted Clock as seen in photo #2.  The face you are purchasing is in photo #1
This reproduction face measures just over 15.5" in diameter and has a hole drilled in the center to allow the clock stem through.
I make lots of other gauge and clock faces for many different brands so have a look at my other items.  If you don't see what you need please ask because I can probably make yours too.
