I guess I will have to add my two cents worth on this topic. I have a very fine silver capped, silver banded, gourd Calabash with a meershaum bowl, Amber stem, and was made in 1912 and sold by BBB.
It is in remarkable shape except that someone in the past became overly enthusiastic in cleaning the bowl out and in doing so cut another hole (slash) in the bottom edge of the bowl. The bowl was originally equiped with three pierced holes in the bottom and it now has an additional "Slash hole" about 3/16" long.(large enough for tobacco to fall through).
To resurrect it I have placed a slightly larger than diameter steel screen into the bowl and pushed it down into the bowl almost to the bottom. It is lightly wedged in there, and can be removed if needed with a little finagaling.
It now smokes again as a beautiful smoking pipe should.
It would be the last one in my meager collection that I would part with!
