I have 20 3 inch butter pats.  The bottoms are stamped “Beatrice” Wood and Son, England. They are in all different condition, but none are chipped or cracked. Some have staining, rust spots, and or crazing. 
You can buy one, several, or all 20. You will receive whichever one I pick off the top of the stack.
