Okay I am here!!!
You are the proud owner of a Singer Model 101. I do have one question is it aluminum? I cant really tell from the photos you submitted. You might have to use a magnet on the machine to find out if it is.
You have a quite rare (in Singers terms) sewing machine, only 230,475 machines made from 1920 to 1932 so it only had a 12 year run.
