NORTH CENTRAL NORTHLINER Herman Sloan Travel Clock A21

Vintage Sloan alarm clock in hard black case with "Northliner Credit Union" and Herman logo lettering.  Northliner Credit Union was the Credit Union for North Central Airlines.  Made in Japan.  Hands of the clock glow as well as a dot by each number on the clock face.  I wound the dial but it didn't do anything, not sure if it can be repaired.  I am selling this as a collector item, not for use.

Case measures approximately 2-3/4" x 2-3/4" x 1"
