Just found out what I needed to know and thought if there were any White owners here they might want to "age" their older machines also............ the toll-free number is 1-800-446-2333 and the hours of operation are 8 a.m. to 4 p.m. Central Standard Time, Monday through Friday. I found that my treadle was manufactured June 7th., 1901 and she's about to be restored. She's a pretty little girl but is in desperate need of a spa treatment - you want to talk about GUNK???
