I have been trying to research about my machine. It seems to that I am missing a piece that helps hold machine to table when it sit in it's section so tables lid can close. I can not put the machine away in table so it sits on table. I am wondering if anyone knows about this type of machine. Singer 1920's Sewing Machine Model 127-3 (Serial #G7945540) with table & treadle model #2. This gem was born in March of 1920 in Elizabeth NJ. Thanks for your time.
