Replacement Storm Door Handle/Lock

Good morning. I would appreciate your help in identifying replacement options for my storm door handle. The handle currently separates from the door if I try to open it too quickly and I'd prefer to replace the handle vs replacing the entire door. Though I thoroughly checked the door and handle, I could not find a brand name or model # for the door. Hopefully the attached pictures prove helpful with your team identifying options.

Thanks in advance and please let me know if you have any questions.
