PCCA was headed up by Bob Hamblin. Bob traveled around to darn near all the pipe shows way back when! IIRC, all the PCCA tobaccos were made/tinned by McClelland to his recipes. Bob also had a website where he sold his tobaccos and a goodly selection of pipes and accessories . I bought a whole slew of his 'baccy's years ago. His Latweeds had both Syrian (Syrian Star) and Cyprian (Cyprian Star). I checked Tobacco Reviews prior to typing this missive. I was surprised to note that Syrian Star was not reviewed, nor was Jazz. I rechecked my PCCA collection, noticing that several other PCCAs in my cellar were not reviewed/listed!
Can't exactly remember when Bob shut down PCCA...15-20 years ago! I realized he was getting out of the business/retiring when he started listing lake front property, etc. for sale on the PCCA site!! He also cleaned out his 'baccy closet; I picked up some grand bargains during this time. McClellands continued making some PCCA blends after Bob retired. I would have to dig further to compile a list of those!
Older Brothers may have more info on Bob & PCCA. FWIW, FTRPLT
