No mystery as to who made this classic gourd Calabash with removable Meerschaum bowl, it's a Kaywoodie. Keeping it smokey with some Mac Baren Club Blend Roll Cut.
Hard to know mso489, it was listed in their catalog and the band appears to be simply aluminum, the stem has their logo and we know that was easily an in house thing. When checking other Calabash pipes from the period these are certainly identifiable as their pipe when compared to others, I'll let someone more versed in Kaywoodie's history give us some information, cheers.
