Parts or dimensions of parts, safety slide spring

[Joe Peace]

I am a gunsmith working at Franklin Gun Shop in Athens, Georgia. We have a Parker Brothers S x S 20 gauge. The gun when purchased would not cock. The trigger spring was badly bent and broken. The safety slide spring was broken in
to pieces withe front piece missing. I made a replacement trigger spring for the two triggers. I tried twice to make a replacement safety slide spring without success due to the multiple support to actions by the spring
Is there a replacement spring or possibly dimensions for the safety slide spring.
Thanks for allowing me to join. I hope someone can help.
