Main Spring Question...

[Sunkist]

I was going through an old parts box and I found a bag with a few mainsprings and rebound springs. About 15 years ago I marked the bag as "stock springs. One of the main springs is lighter colored and ribbed. Did the factory ever make such a spring or did I get a Wolff spring in the wrong bag?

Some come with Wolff springs stock.

Thanks, tomcatt. I'll put it in a 686 this wknd. and see if it feels different than a flat spring.
