the exact date of your model is 1942 and for 19.00 there is a site where you can get the manual if you wanted.
That said there is very little interest or value in old sewing machines. Even the true antiques 100+ yrs are not worth much. I buy the old treatle machines all the time and pay between 5 and 10 dollars for them and use the rot iron bottoms and scrap the heads.
