My father, now deceased, gave me several of his pipes a few years back. The one of interest is a Sasieni pipe pictured below. All I know for sure about it, is that he purchased it in London, in the late '60's, '67 or '68 to be exact. The pipe is actually in real good shape. and after giving the inside of the stem and airway a good cleaning, I have smoked it maybe a half dozen times. Was wondering if it is worth getting professionally restored?
