That's an antique Norm. NICE!
When we were kids, orange juice was a rarity. It was available as only when the shipments came in from CA or Florida.
Mom had the juicer bowl on her MixMaster stand mixer, and she would buy the oranges in the burlap bag (Like 10 Lbs.) and juice them all.
We only got juice in what we called the juice glasses. They were little three belly glases she got from the movie theater, and Mom would fill it only 3/4 of the way. We HAD TO Drink it, and all of it.
If the oranges were bitter, she would let us add sugar, but ONLY IF She allowed it, and agreed the juice was too bitter.Oh! and no straining. You would get the seeds and the pulp.
We would complain, and she said,"God Gave you a built in strainer, (your teeth) so use them!"
