I am after the torsion spring that is used to keep the outer shutter closed on a Pentax Opito SVi. I have contacted Pentax who no longer stock spares.

It is approx9mm long, with 180' legs, the inding dia is apporx 1mm, the thicknes of the spring wire is approx .5mm. The torque of the spring is very weak as its only used to keep 2x plastic pieces of shutter closed until camera opens. I have a picture if it helps. Any ideas? Cheers
