Good question Longbeard ,
This problem happens alot, but with some study you can sometimes come up with the same call again. By looking over some of the other calls that the company has to offer, most times they will make a call that is almost the same but with a different cut in them. If you can find one that you can modify by making the cuts yourself , you will have the same call.
or
Send a custom maker a new call and he can repo the same call with out a lot of trouble.
Now Bob , you have a different problem, as your favorite call is a little more complexed. A call maker would have to get a soother from a baby isle and somehow attach it to a mouth call frame and that could be tough to do LOL
