Return spring on head door handle

[Ray.Yager]

I’m trying to replace a broken return spring for the door handle to the aft cabin head. I’ve totally dismantled the offending handle set looking for markings as to who the mfg was. No luck. Any ideas as to who made these? Attaching a pic of the inside of another set where the spring is not broken.

Radiant is a 1991 Carver Cal 48 MY (4809).

Mine were Perko. Bought a SS spring at hardware store and cut to fit.
