Check this out Air Heads

So I was browsing an Antique Store in the NC Mtns this weekend and found this.

Very interesting what was known in 1905.

This appears to be a Trade Publication (similar to the trade magazines of today)

It is filled with information and articles on Compressed Air. Keep in mind this was the 2nd year of the building of the Panama Canal.

Still reading and looking for articles on C/A for gunning. Interestingly enough, they write an article on “liquid air” Reading through they are refering to “liquid oxygen” but they consider it “air”

Anyone ever come across these?
