WTD - torsion spring for door lock mechanism

Has anyone got one of the above, or can you point me in the direction of a supplier for the small torsion spring that is located between the actuating lever and the lock cylinder of the exterior door handle lock mechanism.

I've looked at McMaster Carr, but their selection doesn't look ideal.

I'll happily buy a complete door handle if that's whats needed.

thanks

I know someone with a totally worn out handle that may sell just the spring.

I will ask on your behalf.
