Assorted Industrial Metal Components with 'Made in Austria' Part

The image displays a collection of various metal components, likely machine parts or tooling, stored loosely within a translucent plastic container. The predominant material appears to be cast iron or a similar darkened, heavy-duty metal, exhibiting a matte, dark grey to black finish, indicative of natural patina and possible industrial use. One prominent component in the foreground is a circular, multi-holed disk with a central hexagonal bolt head, suggesting a rotary or mounting function. This piece has raised lettering that clearly reads "MADE IN AUSTRIA," indicating its country of origin. Another significant component is a cylindrical piece with a roughly textured, darkened surface, featuring a large circular aperture on its side and a threaded internal bore at one end. This piece suggests a housing, coupling, or fixture. Other visible elements include smaller, irregularly shaped metal pieces, some with what appear to be mounting brackets, levers, or clamping mechanisms. The overall condition of the items shows signs of age and use, including surface abrasions, dust accumulation, and a generalized patina consistent with ferrous metals exposed to air over time. There are no obvious signs of severe damage, cracks, or recent repairs, but rather the expected wear of functional industrial components. The craftsmanship appears robust and utilitarian, typical of precision-engineered industrial parts designed for durability rather than aesthetic appeal. Given the 'MADE IN AUSTRIA' marking and the style of the components, it is likely these parts date from the mid-20th century to possibly early 21st century, consistent with a period when such machinery was widely manufactured in European countries.
