The stamp on the balance reads 3240. Is that the same as your number 3440?

I'm not sure I understand your question. If your stamp is 3240, then you would want a 3240 stamp. Keep in mind the stamp only tells you how strong the spring is, it has nothing to do with identifying the balance itself. I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
