Results will vary widely. Usually pipes unstamped or stamped with generic words like Italy, Imported Briar, etc., are seconds. I plucked one out of my local independent pipe shop basket years ago, an unfinished yacht, that the owner assured me was a Savinelli, at an excellent price, and George knows his stuff. I still have it years later. It has colored into a deep finish that looks stained with a high polish, with no added wax and just hand polishing over the years. It is clearly a Savinelli 404 shape and an excellent smoker.
Other basket pipes can be poorly made. You just have to look at enough good quality pipes while window shopping to tell the difference. Look at many more pipes than you buy.
