This is all the information that I have, but note it dates back to 2008. I don't think the Red Wolfe gobble call is made anymore. The reed is an integral part of the replacement sound chamber, so I don't think it is a simple matter of just replacing a reed. The rubber tube portion of mine has gotten a little stiff, so I can get the best gobble out of pumping it instead of shaking it side to side. I might try restoring it by applying some LaCrosse rubber boot treatment on the rubber bell.
