Good Morning All! I hope ejames sees and responds to this particular topic since I read somewhere else on the forums that he is the resident Dr. Grabow guru. Anyway, I'm currently restoring two Dr. Grabow Golden Duke “Ajustomatic" pipes with the patent #'s stamped in the briar. What's the best way to preserve all these stampings during the sanding/prepping process? Beyond being super duper careful...are ther any tricks?
