What I said was what I was taught many decades ago, not an inference.
If you know otherwise, so be it. I have no intention to get into a
pi--ing contest with anyone over this or anything else. I am not the FAA.

Yes, lets not get in to that type of contest. At my age I no longer
have the equipment to participate. It was not a personal attach so
no need to get defensive.
This thread started with a poorly stated question, that being a
"whiskey compass". There is no requirement for a "Whisky" compass (
or wet compass) , simply a "magnetic direction indicator". To be
absolutely correct the fluid is alcohol, kerosene, or some similar
substance. I was not replying to wet, dry, or any other type, but to
your reply (stated below) assigning requirements to a compass
(magnetic direction indicator) that simply are not stated in the
regs. If you were taught many years ago that the qualifications
stated below are requirements then I would infer that your were
instructed incorrectly. No fault of the student. As a final note, a
wet compass can fail. I have 4 dry compasses in the garage and a
refill kit in the tool chest to recover from such failures.
