I was going through an old box of parts and found a set of bright yellow springs. No markings or stripes visible.

Anyone have an idea what these might be?

measure them and sit on them. you might be able to get close guess to the spring rate.

Spring rates are in pounds per inch of deflection. Scales measure pounds, rulers (or tape measures) measure inches. I'm sure you can figure out the rest...

(Do a search on here and you'll find info on how to measure.)
