This is the first in a series of pieces of business paper for C. B. Stalnaker. He was known as "Charlie" in the oil extraction business of the early 30's, 40's and very early 50's of Northern Montana and Southern Alberta and Saskatchewan. I have an image of a device with this label on it, and I also have a piece of Charlie's business paper that specifies this very device - a torpedo - by name. This one has some information missing or I could actually point to a spot on the map where he used 35 quarts of oil explosive - nitroglycerin - to improve the output of the well. Charlie was an expert. He died in bed at the age of 87.
