Thanks for posting, Larry. The stamps you gave us are only indicative of the strength of the spring. They're not product codes or anything. What's more is that the only numbers that matter are "29-3," you can ignore the rest.

That's about all I can tell form this information, though. In order to determine the Series, we'll need to see clear photos of the top and bottom nylon fitting.
