Estate Find - most film reels have been dated late 50s, and very few early 60s, so I'm estimating this to be likely late 50s or possibly early 60s. Navy sailors taking a break at a swimming pool at a stop in Haiti. 

8mm Movie Film Reel - about one minute 15 seconds of footage.

Film played ok for me and has no vinegar smell to it, but it is vintage, going on 60+ years old, and inherently is at risk like any old film for issues with condition and integrity.
