This surface mount Storm door handle set has been discontinued
Used by Marvin and others

There are several options that might work
Option # 1
If you want Brass, Nickel or Bronze
303052 Plated Bright Brass
303051 Solid Polished Brass, Nickel and Bronze finishes
You would have to drill a hole in the door edge and the backset would be 1-3/4 inch
Your door is most likely drilled for a 3/4 inch backset and you would have to fill some of the existing holes, or use a plate to cover them

Option # 2
303056 Silver Finish
303057 Silver Finish
These are surface mount and will most likely fit the basic holes in your door

There are some other options, but all require some modification.
