For a start the 4200 and 3200 are quite different, I suspect this is a 4200 sensor as they are a bit less than the 3200, and since it's used it has been replaced, so it may already be faulty. I have one like this in my garage, I think it cost me 50 quid!
Hi Davyi still make pedal sensors if that's what you are after. they are alternative parts and not refurbished.
Hi Davy
