F W Means retirement fund in Chicago, Illinois?

[tennesseedean]

Hi, My mother worked for F W Means in South Bend Indiana in the early 70's and was supposed to have qualified for a retirement package but can not locate any info as to who is honoring their retirement fund. Does anyone know who to contact for this info? Though the company went out of business years ago, is there a way she can collect what she is owed? Thank you
