The top pipe is a Peterson that I picked up off of Ebay a month or two ago. It's an African Block Meer. (A great smoker , BTW) The bottom one I just got last week. It is a Carey Magic Inch and to me at least it also looks an awful lot like an African Block Meer. I'd like to replace the silly little magic inch filter assembly and stem with a Peterson or Peterson-like (doesn't have to be a P-lip) bent stem. This picture shows both with the stems removed. The Peterson stem on the straight pipe is an exact fit for the bent one. I don't know much about sizing the stems. Does anyone know what that size would be and where I can pick up a bent stem of this size? I know I can just put tape over the air slots and smoke it but I'd rather replace the stem if I can.
