Exactly, Andi,
I know their experts very well.
Like 99 per cent of all museum curators, they are art historians, and consequently do not know a thing about weapons in general, let alone earliest firearms!
Actually, they condemn weapons, and they despise everybody who is interested in those objects!

And that's a fact.
It's the same sad old story in any museum, wherever you go ...
And, of course, they do not care either ...
Best,
Michael
