Need this Old Sears Handle Set

Hopefully I can help! I am afraid your old Sears Storm Door Handle Set isn't made anymore. We do, however, have a substitute. Look at the 40-131 lever handle set with deadbolt. This is similar to yours, but without a key cylinder to unlock it from the out side. If you want key access, you would need to install the 40-058 lever handle with dead bolt.
