It does look like some kind of dried oil; someone probably slathered way too much on at some point and just left it to dry. Try ethanol, maybe?

Try ethanol with something light to scrub. Toothbrushes are one if my favorite tools for sword cleaning.

I've encountered antique blades that had been lacquered before storage, and age had turned the lacquer shades of yellow and brown. Acetone or lacquer thinner worked to remove it in my case.

Yeah, if ethanol doesn't work, acetone might.

Started in the 19th C. and went on for ages: Clear lacquer and cellulose based mostly, so that turned a nasty brown over time. Fairly thick coatings. In France they still do it. The old guard that is. Acetone may help, paint thinners, that kind of stuff. Try to do it outside with really clean rags. No scratching. First go the chemical way. If that does not help I need a close up image of a spot to determine how to proceed further. For now, do not try sanding. It can and will do damage. Hope this helps a bit. If not just PM me. Good luck.

I am not familiar with European customs but could it be cosmoline?
If so, I found this on Wikipedia:
Freshly applied cosmoline, or that which is hermetically sealed in a plastic bag or shrink wrap, retains its grease-like viscosity and wipes near clean with a rag, leaving only a thin film behind. Older cosmoline which has had air exposure usually solidifies after a few years, once its volatile hydrocarbon fraction evaporates and leaves behind only the waxy remainder. This solid wax does not readily wipe off. It can be removed with laborious scraping but leaves crumbs to be swept or vacuumed away. Application of gentle heat sufficient to melt the waxy hydrocarbons allows cosmoline to drip off. Penetrating oil (such as WD-40 or CRC 5-56 CLP) sprayed and allowed to soak in until cosmoline is restored to a viscous-fluid state allows it to be wiped off. A closed-cabinet parts washer may be used to power wash smaller items. An aqueous rather than petrochemical based wash requires high heat, the proper aqueous detergent, and the correct hydraulic impact pressure.[4]
Soldiers in field conditions have often used gasoline or other handy petroleum-based solvent (such as kerosene) to clean cosmoline off stored weapons.[5]
It is not recommended to use harsh chemical solvents that could strip paint, finishes, or other aesthetic/functional coatings from the gun's surface. A better solvent is Stoddard Solvent, or mineral spirits. Complete instructions can be found on Cosmoline's official site.[6]

pgandy makes a good point for cosmoline. Have bought quite a few WWI and WWII East European and Chinese firearms that were packed in cosmoline. Some were easy to clean but most took some time. Some had to be soaked overnight to get most of it off.

I have uses purple Zep degreaser on Cosmolene, you could try something similar on a small part of the metal. Follow the safety instructions, it isn't healthy stuff.

Good for you! Old varnish can be hard as nails. Cosmoline.... I have to remember that.

I think any old, and I mean old, soldier has cosmoline etched in his mind. The government used tons of the stuff. Those days are gone. You young whippersnappers…????

Back in my day at the turn of the millennium, at least up here in the frozen North, we just used gun oil. Probably not least 'cos it doesn't freeze in -50C.

Cosmoline was use for long term storage.
