When buying pipes at a premium price I always look for same with original stems. Logos some times missing because of careless buffing. When I ask some sellers on e bay when in doubt the common answer is they have limited knowledge in this area but whimidhedkmodhefen looking at others in the store they seem to have know a lot about pipes. I know that buyer beware comes into play here but are others here share my opinion that fellow collectors shy away from these pipes because of deminished value ?
