A friend of mine gave me a Morgan tube caller last week. It is the Mahogany tube with the metal top half moon in a metal tube carring case like the one on Morgan inactive site. There is nothing else in the sound chamber. Is this call missing any metal guts as described below? " a metallic flange has been built into the inside to enhance resonance of the mahogany chamber." I dont have this. only metal i have is the top. Any help or explanation would be greatly appreciated? thanks
Morgan Tube description
Our original patent of having a metal sleeve imbedded within a wood cylinder cut to the precise length of a resonating air column is still the basis for this unique turkey caller. We have made some changes; the old snuff can has been replaced with a fine rust proof alloy sleeve, a metallic flange has been built into the inside to enhance resonance of the mahogany chamber. This caller will reproduce virtually all of the turkey language, including a most realistic gobble and an unmatched lonesome hen yelp which can be heard for incredible distances by turkeys. It comes with a lanyard, a camouflaged carrying case, and extra latex. It is a must for the serious turkey hunter. Video instructions are available here.
