Antique Masonic Past Masters Pin 1916 1917 Dewitt Nebraska Lodge 111 Masons

We have for sale a vintage pin dated 1916/1917. What you see in the pictures is exactly what you will receive. This is not marked as far as gold content. I did an acid test, and the lower half shows as being 10k. I cannot find a mark on it. This is vintage in vintage condition. Please look at all pictures closely for details and measurements, thanks for looking!
