I agree there are some really technically impressive and interesting things made in Germany 1933-45, not least weapons. And they are worth having in a collection.
What I don’t get (well, I think I do, but heavily dislike it and think it’s unhealthy) is why, say, where legal, a Walther PP made for the police in 1932 is worth less than an identical 1941 one with Nazi markings and provenance (former used to apprehend criminals, latter to shoot Jews in the back of the head). Or the fascination with SS etc dress daggers, whether real, fake, or repro.
Also, a lot of those companies did make a choice - to employ slave labour.
Getting off soapbox. Dinner awaits.
