Under the category of "not-beautiful":
A late 7mm Oviedo Model 1893 Spanish Mauser (1927). Last year of production of complete new M'93 rifles seems to be 1298.
Needs help! But maybe it'll still shoot.
At least it's unmodified. And cheap...but hopefully chock full of educational and minimal cost labor-consuming (i.e. scrubbing and cleaning) value.
It's surely not Germanic craftsmanship, but not as bad as first thought.
