I photographed this machine at a yard sale last summer. The owner surmised that it was for cutting cloth. There was no maker's name, aside from a place on the base where a decal might have once resided. The only text was the label above. "BBL" is the abbreviation for an oil barrel. (No one seems to know why "barrel" would be abbreviated in this fashion. The "b" may have been doubled originally to indicate the plural (1 bl, 2 bbl), or possibly it was doubled to eliminate any confusion with bl as a symbol for the bale.) In any event, today it can also stand for "Broadband light" or for "Be back later." Different times, different meanings. BBL!
