I visited Leica's Factory in Solms* a number of years ago and the actual construction of a small number of Leica Rangefinders are handled by around 10 or so workers each responsible for installation and calibrating various optical/electronic components and making sure they were within tolerances as they were installed into the camera shell. A lot of their Lenses are ground on site from blanks. Lens barrels are machined and DOF markings carefully painted (with what I take to be some sort of hard setting enamel) and the whole lens hand assembled and tested by a group of workers designated to build and finish a specific optic. An expensive way of doing things, but the results speak for themselves.
Another example would be the Flutes I play on, which are handmade, the manufacturer of one of my flutes (Altus, based in Azumino Japan) a single worker can spend 6 months and up to year meticulously building a single instrument to order**. This manufacturer also do make a separate line of instruments (Azumi) that are largely machine made, albeit hand finished and possess similar qualities to their handmade instruments for a lower price than fully handmade instruments.
* I have also been to Leica's Wetzlar factory, where they serviced my grandfathers 60 year old Leica M3 and replaced some components with NEW parts they still had on hand.
** Yes, it can take that long - Backorders are common with high-demand instrument makers. Instrument mechanisms require extremely high tolerances to move smoothly and Altus technicians make
everything by hand. Custom alloys of gold such as 12K 16.7K 19.5K red gold (even 24K has been used, even though it is soft as hell) it often has to be prepared and smelted by hand and exceptionally hard alloys of Platinum and Iridium (which is notoriously difficult to work with) are typically left off official price lists, but can be ordered.
