Got some killer acrylic in and wanted to make a couple calls...the crow caller has a sterling silver reed and the mouthpieces are made from African Blackwood, the Killer Keg has the brass insert (just have to wait on my oxygen tank to get the lip rest soldered in place) it is baffled. Sanitorium and I have a running contest each year on who can make the better call submitted, this year we chose the crow call as our competition, look out Nashville! pappy
