World War II brought about many changes at Kaywoodie, as it did at most other American companies. Faced with shortages of briar and aluminum, the company used expedient sources and methods to maintain production. The most notable of these was the Kaywoodie Mission Briar pipe, which used manzanita burl harvested in California. These pipes are stamped Monterey and Mission Briar, with the white logos, some with bars and dots in the end, in various configurations. Most were not stamped with shape numbers. I have a 1946 Monterey Pipes pamphlet that also has Kaufman Brother & Bondy printed on it. There were 4 grades shown in the pamphlet. The highest price was the "Forty-Niner". It came in a natural finish with a wide aluminum ferrule like the Kaywoodie Centennials and Ninety-Fiver. The stem logo was two offset lines running in the lengthwise direction on the side of the stem. They were priced at $10. Next was the Carburetor Virgin Grain Monterey. Same stem logo as the Forty-Niner, but without the wide aluminum ferrule, priced at $7.50. The Specimen Grain was a medium brown color with a stem logo on the side of the stem. It was one long line with a small dot at the end closest to the briar shank. Price $5. The last in the line was the Select Grain, priced at $3.50, these were dark plum color and had a stem logo on top of the stem that was one thin line running across the stem.
