I'm interested in this thread. It sure does need photos though
I recently decided to get a manual hand grinder, not a vintage one. Just a Hario Mini Slim, I must admit, I'm not happy with it. I'm on my second one, both have failed me, and the grind consistency is shockingly bad and just not suitable for good filter coffee brewing. I've just ordered a porlex so hopefully this is an improvement.
Always looking at vintage grinders, so quite interested to see some examples. There's something cool about hand-cranking to grind
