Welcome, Elizabeth. What kind of information are you wanting? Does the A have a number after it? A picture would help, I believe that some serial numbers are on the front slide plate and some in the bed underneath the front slide plate.
There are many threads here on Quilting Board about Minnesota sewing machines. There were several different Minnesota models which were sold by Sears and five versions of the Model A.
Need help identifying Sears Minnesota treadle sewing machine That is in the thread
Need help identifying Sears Minnesota treadle sewing machine which has several good posts in it about Minnesota machines other than the opening poster's. Some others include:
Minnesota A Treadle
Vintage Minnesota Treadle
Newly purchased Minnesota "A" treadle
MY Sears Minnesota sewing machine!
We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.
