My Colt Officer's Model 2nd Issue is from 1917. S#417412.

The medallions are deep set and look like they were originally gold and are turning silver with wear. I see the Blue Book says these type of grips were standard from 1913-1923. I'll have to work on resizing photos with my next post!
Thank you bdgreen for your excellent tutorial on posting pictures!
