I remember being sick at home as a kid in the mid-60's and the Family Doctor coming to our house. My parents had that same doctor for proabaly 40 years and his office was always in a couple of rooms off of his residence. I remember him as a gruff old guy but very personable as he knew you for the moment you were born (no keeping secrets from this doctor).

My boss has a similar metal First Aid Kit (white tin box, green lettering) to the one you showed. It was issued to Forestry Workers/Forest Firefighters around the 1960's, I have try and talk him out of it before he retires soon.
