Man, I remember those, getting one under the Christmas tree in the late 60’s. Glad you mentioned that last part, too. I got two cases of two different Mr. Beer homebrew ales in the garage fridge. I brewed and fermented them then put them in there to condition back around Thanksgiving. I gotta drink them before they get skunky. I bet the ABV is probably in double digits by now (I overcharged them with carbonation drops).
I had one in the 1960s. They are still made by another company.
(Yeah, I know Amazon but it is just for demonstration purposes)
