Hey BadP, I can help you with that CS-35 drum. The spring is technically a Cold Rolled Spring Steel Strip.



But if you're trying to replace it with a generic equivalent, the actual physical description may be more difficult to ascertain. You have to take into account Yield, Hardness, and in some cases Composition, in addition to its length and width. I doubt you're going to find a decent substitute.

If it's broken, it's probably best to swap it with another genuine Nerf replacement. There are occasionally broken CS-35s on Ebay. You might consider picking one up cheap and cannibalizing the spring.
