@douro20 They didn't have steels like we have today, so "overbuild" was necessity. Also things were built to last.

@RyTrapp0 Valid reasons, I aggree.

Bolt action LMG? Crazy knurling, all tho it look like it's cutted. Are you sure that is French and not Swiss? Must have been very expensive.

@gaslyktan It's French not Swiss.

That is mostly because machines back then are only able to do simple cuts.

@lairdcummings9092 Modern multi-axis CNC machines gives you much more freedom to design parts. You can do cuts that were impossible then. If you can't do a needed cut in one way, then you need to redesign your part. Instead of one relatively simple part, you have to make many different parts. Anyone can design a complex machine with lots of parts, but to make the same task simple and fewer parts require much more.

@lairdcummings9092 You can do lot of things with manual lathe or milling machine, but it often is not practical. Let's think something simple, a hemisphere. Totally doable with a manual mill, but also highly impractical, especially for a mass production. So that leaves you two options. 1. You do it. 2. You redesign the parts. A thing that machinists still come across today is an engineer without machinist's background. They often want a triangle hole with 90° angle through a sphere and of course not the center. Modern machines still need a good operators. Not all the time, but someone has to do the first part. You need to know how to cut and when. Skills needed today are different than then, but still skills.

@lairdcummings9092 I didn't said difficult. I said impractical.
