My technique of finding high quality logos involved looking for PDFs with logos embedded into them and then importing it to Illustrator. Earnings statements and digital product catalogs have interesting logos too like Bluetooth and CE/UL marks. It’s not exactly like the original but close enough. It’s enough to take the DWG into AutoCAD or CAD/CAM to generate high quality vinyl decals.

I can’t tell how close to the original these logos are without comparing them in AutoCAD. Perhaps there should be a source cited for each upload to improve this site.

By the way, for regular lines, SVG can be a good substitute but all CAD software and file formats treat splines differently. You need to store a bitmap copy to make sure something doesn’t get mangled up because of conversion. SVG surely does that. Native files will usually show all the construction lines involved in producing the details. That would be the proof that you’re the proper trademark holder.

What is the precision we’re using too? There should be some sort of standard there too. E.g. SVG16 to indicate precision.

My interest is in generative AI in the field of vector graphics. There’s a lot we can do there.

SVG does not store a bitmap. They are XML files and you can inspect the source code.

Au contraire, you very much can embed bitmaps into SVGs - it's often the only way to export gradient meshes in a manner supported by all renderers. This can be done via the plain ol' `image` tag with an external file, or a data URI to directly embed the encoded bitmap file.

If you want to be extra cursed, you can also place a bunch of 1x1 `<rect>`s next to each other and color them individually. For extra points, you can combine consecutive pixel of the same color into a say 2x1 or 1x5 rects. Or make use of `<use>` tags to implement a color pallete.

There is also https://www.brandsoftheworld.com with a lot of logotypes including old ones.
