So this last Sunday my grandpa gave me his dr grabow pipe and I was so happy about it! It has "duke" engraved and is a bent pipe. It is a lot smaller than my two other pipes which perfectly fills my need for a smaller bowl shorter smoke. It also has the blue spade on it which from what I read denotes a filter pipe. I know it's a cheaper brand but obviously it now has huge sentimental value. Any have experience with this particular DG model? I'm a newcomer to the hobby but I must say it smokes really well and is a fine looking pipe. I know there's a ton of info to read on the DG duke pipes but I'd like to hear what you all have to say about this model. I've smoked two bowls of 1Q and one of sutliff vanilla custard and all times it smoked great! Would love to hear your opinions!
