I just looked, and you are correct. There are 2 sellers with brand new lock cylinders for the '65 and earlier cars. The ones listed are the '65 version, but, they will fit fine on the earlier models too. They just look a little different with the concave face instead of the flat face. Not sure who is making them. Neither seller says if they're USA, China, or from some other country. Pretty spendy price tag for them however. I can re-key all 3 used cylinders for less than half what they want for the new ones. Good option if yours are broken though, as individual parts to repair them are virtually non-existent.
