Models we've catalogued

How to read this. Specs come from each maker's own spec page or datasheet, with the link and the date we checked it. Blank means the maker doesn't publish it (or we haven't found it). Scores are a whirrwork assessment, not a lab test: we only score a model when independent trials or tests exist. Methodology.
