Coors mortars with lip (# 60310 and # 60316), and pestle # 60311. There are initials (bottom of mortars), and on pestle. Don't know what they signify, perhaps the lab (?). Measurements (approx.) are- # 60310 is 1 7/8" tall, and # 60316 is 2 7/8" tall. The pestle (#60311) is 4 1/2" in length. Very good condition. No chips or cracks. Please refer to photos.
