Wow! Flash from the past and memories of going with my Mom to Plummer's fabric store in Springfield MO where they had those AND the pneumatic tube set-up. They also had some round, hollow tables with fabric bolts shelved on the and I'd duck into the center and hide--and get yelled at! We went there often cause my Mom sewed all our clothing--my Dad is the only one that wore ready made cause he wore work clothes.
