I have a Goodrich PH-2 for sale.
I'm not entirely sure what the situation is with this.
I believe it was originally a photocell pedal, based on the info I can find, but has been converted to a pot pedal.
It does have a transformer and needs to be plugged in to work, so it likely has a buffer circuit, as well.
It is missing the rubber feet.
I do not know what pot is in it, but the taper isn't great, so it could probably use a new one.
