I have 5 Singer 221s. One green 1964 with white/green case, which I was given by my mother so she could teach me to sew back in 1964. Two black ones dated 1950 and 1953 both given to me by my neighbor...for FREE, including cases. I bought 2 non-working ones from an antique store to strip and restore. Still working on those.
Plan on giving all of them to my grandchildren when I teach each of them to sew. They are all too young to have them now. Wait another 3 years and they will be happy to have them.
