Congrats on getting a 603! I have a Singer Slant-O-Matic 603 Special that my Mom bought in 1963. That's when it must have been made as the copyright date on the instruction manual is 1963. I learned how to sew on this machine and sometime in the late 1970s, my Mom gave it to me when she bought a newer model Singer. I am now 50 and am still using this machine. I love it. It is a workhorse of a machine. It has been to the "sewing machine hospital" a couple of times for adjustments and maintenance, but it has been a joy of a machine to work on. Use it and enjoy!!
