Machine registry

A running index of grinding and machine-tool models attested in this archive’s documents and in the site’s builder research — each row gives the model, the maker, the machine type, an estimated production period, and where the machine is attested. Years are estimates and say so; a machine is listed only when a source in hand names it. Where a maker name changed over a machine’s life, each era gets its own row. The registry is the seed of a future repair-knowledge project: a record of what machines exist, kept honest, before any repair history is attached to them.

53 models are indexed so far. The registry itself is a plain file — download the CSV — and it grows with the archive’s monthly sweep. Corrections are welcome through the contact form; the record is the standard, and it is kept honest.
