Steinar,
I have some oldstyle Dutch military grade gun oil.
It's no longer in use by the army because it's not really healthy to use it on a regular basis.
I'd be happy to send you a sample for the test, as I have been using this stuff for years (just not in dangerous quantities
). Made in 'Zwijndrecht'.
I can also get you a dab of Swiss gun grease, as found in the Swiss gun cleaning kits.
