1940's Selmer Air Flow Metal 1st GenerationHere is a rare, original condition 1940's Selmer "Table C" tenor mouthpiece. This mouthpiece measures . 063" on my gauge. These first generation metal Selmer mouthpieces are about as beautiful as they come. Elaborate decoration on the shank, unique fluting on the sides and a squeeze chamber that was futuristic compared to the very large chambers being made in the U. S. This would be a nice mouthpiece for a collector looking to match original equipment
