I have McPherson parts
I have five McPherson heavy brass valves for the upflush toilet assemblies. They are all supposedly rebuilt, according to the previous owner of the house. We never used the toilets because the pressure pump went out before we even bought the house. The valves have a tiny bit of surface corrosion on the outside of the valves, but the insides do look new (bright white plastic, brass not corroded, etc.) If anyone needs these valves, please email me with an offer.
