Filter tap cartridge (Melbourne DE73)

Triflow TF321 Screw Fit Filter Cartridge (FRX02 / FR9455). We have had to have our Triflow kitchen tap replaced. We still have a brand new spare filter cartridge left for the old tap. It does not fit our new tap but maybe someone can use it? They cost about £45 each. Available for collection any time. We live in Melbourne.
