Scales - I remember that my Grandma had a kitchen scale.  She lived in the country and grew an enormous garden, and often sold veggies to the neighbors.  They would come by, express their wants and out came the bread sacks (everything was recycled) and filled with squash, okra, ect.  They were promptly weighed and the money was put into the sugar bowl.  It was a fun day when a kid to got to count the change in that sugar bowl.  Sweet memories!
