DR Nunn's Black Oil Healing Compound/Balsam
All the diggers said Dr Nuns were Utah bottles. "But what is it?....Well...."..They are not the most rare but certainly uncommon and a bit of a mystery. Then in a shop on the way home, I found this little get to help put the discussion to rest:
The Label States:
Nunn's Black Oil Compound. A good hoof oil. Est.in Utah 1873.
Ingredients: Raw Linseed Oil, Turpentine, Flour of Sulphur, Kerosene,1/4 of 1% Phenol.
Directions as a hoof oil: Clean hoofs well and be sure they are dry. Soak with Nunns Black Oil. On cuts, Abrasions, Etc, apply liberally with well saturated gauze.
Nunns Black Oil Company, Salt Lake City.
The back label is not as clear but it says the "Same Nunn's Black Oil you have been using for 95 years"
"Flies will not bother wounds treated with Nunn's Black Oil."
External Use Only
These are definitely Utah Bottles.
The labeled one is machine made and if the 95 years was from 1873, then it was produced in the 1960's.
The common size is the smaller one at 5.5". The larger one is 7.5" and is much harder to find.
Looking from left to right on the photo below you will notice that variation in color. The far right is a grey smoky clear bottle. A rare color. Next is the amethyst and the next two are sligthly different shades of aqua.
