There are similar brand new walking feet for older machines. They are made to align better with the narrow feed dogs of straight stitch machines. The feed back on them is usually positive, by far. Complaints are more in the direction of durability, some are less plasticky than others. Some find any walking foot work and it doesn't matter much. Which model do you have? The most talked about models tend to be model 66 or the 201, but should work with any of the old low shank machines.
