Hobb's version shows up frequently, especially the small square dishes/ bowls. Still good sellers today. The large Gillinder bowls are scarce no matter what the color. I do not know of any accounting done on individual patterns of any U.S. glassworks. To say that tons were made in any given pattern I would guess to be accurate.
Given the division of labor in glassworks at the time [1880's]. I am sure the young carry in/carry out boys were quite busy. These young boys would do the mundane work in most glassworks. Carrying glassware in/out of the lehr, opening/closing molds, etc. Harsh by our standards today. it sure beat working in the coal mines.
This decade [1880's] was one of large economic expansion in the U.S. The last "panic" as they use to call them, was the early/mid 1870's. The next one to come early/mid 1890's.
