“A high quality motor with a strong metal gearbox. They were smaller than I expected - width and height (as viewed end on) are 10mm and 12mm.
The gearing means you can't rotate the output shaft by hand if that makes any difference to your project. That might be useful to me, so I'm going to play around with the 50:1 and 298:1 versions to see if I can get different gear ratios. I suspect this is possible.”
