Is it my eyes, or does the thing in the circle not look like a swastika, but more like a four pointed ‘star’?
I mean, I am gettin’ OLD…

I think I am at least as old as you as I also see a star

This is meant to be a swastika but due to time saving measures in bunter production was stylized.
Also observed as a dot and sometimes omitted in total.

I have not heard of a star being used to indicate a Nazi swastika, nor a dot.
How would one know if it is meant to be [a star or dot as] a swastika, as those marks have been used by other makers, not necessarily for Germany?

No star to repalce a swastika in Germany!
Stars were used sometimes but not in relation to the accpetance mark.

Other manufacturers are identifyable by many other features.
And none of them used eagles etc.

Jack, no. I said the Swastika was never featured as a star. But stars were used in other hs positions to indicate technical details.
Two different things!
