Grand ledge chair co. Wood chair

I bought two chairs at a thrift store that have tags on the bottom that say Grand Ledge Chair Co. Grand Ledge, Mich.  The model number is not visible.  In chalk on the bottom of one chair are the numbers 7048 and 242, and on the other 7048 and 241.  They are 38" tall and 14" deep.  I have found some information on the chair company but haven't found any on the chairs themselves, including use (dining chair, desk chair etc.) or value.  Any information would be helpful!
