Marv, if you look online, you can find a few alternatives to the Call Purrfect system (Feather Ridge and Lil Jiggy come to mind right off the bat). Although I think the CP jig was good idea at the time, I think there are updated and better call-making jigs available, and I think they probably accept the more commonly used frames that are sold today from at least a couple of sources.
At one time, long ago, I had the Call Purrfect jig. In my opinion, it is just too limited in what you can do,...mainly related to reed tensioning,...and I moved on from it pretty quickly. I think you would find one of the newer jig (or press) systems to be much more flexible in what you can do with them, as well as having many more options in terms of call frames and sizes.
Finally, I would not be surprised if you cannot get those specific frames for the CP system much longer. You should probably look seriously as changing to a different jig or press. I think you would be happy with that decision over the long run.
