Even industrial quality control is done via random test. The only questionable part being this: for large production volume, the sampling space of 2 sounds too small. Probably test a few hundred will give more reliable result. But this still reveals certain issues.

Finish on wartime production is usually lower. People could understand that finish being secondary at wartime, so finish was sacrificed. That makes perfect sense. But there is an assumption -- "this was controlled lower". But in late war time, (1) quality did not have to be still under control; (2) quality issue may not limited within finish only. If saying "I still have control on everything, but I just lower finish alone to fit wartime volume", that's simply too ideal. In real world, quality is a systemic thing. It's regarding the quality of the whole supply chain, not a single factory. In theory, lower wartime quality actually makes sense. Combined with today's random test in practice... what else can we do to make conclusion more sound...
