Good Eyes Tom,
Yes that's the lower half of a Nicro vacuum coffee brewer, the upper chamber is in the sink at the moment. Funny, I asked my Mom about this coffee maker just the other day. Obviously at 11 I was too young to be drinking it, but the unit hung around the house until the 1990's when it was tossed. (UGH).
Mom said it made the best coffee, far superior to percolators that were common at the time. She also prefered it since it couldn't be broken like glass units.
For various reasons (Dad), she had to give in to the Mr. Coffee drip system, which she never really liked as well. She hung on to the old Nicro for years, but discovered that the rubber collar on the vacuum tower was breaking down, so that was the end of that.
