Hello Folks! My Dad's collection included the below Kaywoodies. Does anyone know about how old these are? Any information would truly be awsome! I strive to list items as accurately as possible and want to be sure I include as much info as possible. Having a whole forum of experts is truly awsome! Thank you all for your help!! The frist one is stamped "DRINKLESS KAYWOODIE, IMPORTED BRIAR", the second one is a metal stem with clover on the mouthpiece and the last one is stamped "KAYWOODIE RELIEF GRAIN" with a clover on the stem/mouth piece.
