Monon H-10-44 #18 was sold to the W. R. Grace Company in 1963. In the 30+ years of collecting former-Monon locomotive photos, I have only found two of #18 in W. R. Grace colors. The locomotive was repainted and renumbered 102 by W. R. Grace and operated primarily in FL. It was scrapped in 1968.
The caption for the first photo is "Mulberry, FL; 3/06/66".
I will send the second photo in the next post.
