I found an interesting and enjoyable article about analog tuning methods here: https://drive.google.com/file/d/1QpsnVZoIx0WZYqWHiVsQWWDgv3l3E1t4/view , with a brief overview of the article here: https://swling.com/blog/2021/08/bob-colegrove-on-the-joys-and-challenges-of-tuning-analog-radios/ .
At some point (hopefully soon?) I need to plan the mechanical tuning arrangement for my homebrew shortwave superhet. I don't want to use a digital frequency counter and would prefer to stick to analog methods. The document linked above provides a nice overview of different methods and issues that occur when implementing an analog frequency dial.
Another source for analog capacitors, reduction drives, pointers, etc.
