Just to clarify, I listed the 1900 catalog because it did not have the Red Gun Oil, it had 3 in 1 Oil listed and pictured, my next catalog is 1902 and it has it, so Red Gun Oil came out between 1900 & 1902.
Now instead of clarifying this will confuse things.
The 1902 catalog has the size listed, 3oz...the 1903 does not list a size and drops the price.. so was the oil just cheaper are were the bottles made smaller? Is there more than one size of bottle?
The catalogs that picture the bottles show what looks like a paper label, I've seen one bottle with a paper label still intact - I think it also had the molded in writing on the other side, but not sure... so, did all the bottles originally have a paper label? The label pictured in the 1903 catalog is different than the one in #15 ~1905~... were there different paper labels?
Attached are copies of the catalog pages, there is also some interesting information about the steel used in gun barrels in the 1900 & 1902 pages.
