My first several years of flying were in the military, when all we had
were Adcock range approaches and NDB (we called them ADF) approaches.
We did them to 200' and 1/4 mile. Sounds hard to believe today, but
we took it for granted.

So ILS mins of 200 and 1/2 seem quite reasonable.

You had ADF? You lucky guy!
We had to find the cone of silence, turn to the appropriate heading,
and make a timed descent to visual contact with the airport.
I don't remember the minima, but I think they were higher than 200+1/4.
