Thanks guys. These old African Block Peterson Meerschaums are getting harder to find since the Laxey mines shut down in '06. Eaglerico, this Pipe's color was applied at the factory, ergo the 'Tawney' designation. African Block typically is a mottled grey unlike the high grade Turkish Block, so most African Block Meerschaums received pigment coloration at the factory. They are also heavier not only due to the inclusion of minerals and aggregate material in the Block, but they were 'Calcinated' after being carved, to give them greater strength and durability. They will color with smoking and the use of Beeswax, but it will be more of a gradual process than high grade Turkish Block. They make great roustabout Pipes that smoke well and don't require a lot of care to perform well. I've seen them color all the way to black but I can't say how many owners that Pipe served. The amazing thing about this one is that it has been well cared for and even has the box. Typically, these Pipes have been neglected and abused, so this one is an especially rare find. A few years ago, I saw a 1970's Facet cut Peterson go for over $350 US, but it was well colored and the bit didn't have any marks on it whatsoever... Like I said, I saw it but passed on the opportunity....
