I asked the seller:
hi, is this an actual Brompton pedal. It might help if not, because I am looking for pedal to add powergrips too (might you have a side on pic?)
Do you know the weight and might you have a buy-it-now price (I live in M20 so can even collect).

Hello, they are not marked as brompton, but this is taken off a brompton bike, and im not sure if there are any other fold away pedals with the same square attachment. The weight i don't have anything to weigh it with, but they feel very weighty compared to your average pedal. i'll upload a 3rd picture on sunday for you from a side view.
