vintage Porcelier ironstone china dripolator coffee filter basket, replacement parts

Old drip o lator coffee pot chamber (5 1/2"tall) for a vintage Porcelier pot, showing some star crazing lines and discoloration, but should work without a problem... these are getting hard to find, even though the Porcelier pots themselves last forever! This has the small interior cover which we almost never see, and this piece is in very good shape.
