John,
Although we live in North Carolina now, my mother still has contacts in the Jacksonville area and was made aware of your project.
Enclosed are three pictures we found in a photo album she gave me. These photos were taken in December 1954 and was the first time of many that I visited the little train in Mandarin when we lived in Florida.
01 - Picture of the train

02 - My mother and me at 6 months in one of the open
cars

03 - Me being held on top of the caboose
