Hello, I have acquired a second-hand Mamas and Papas Pliko P3, dating from 2007. I checked I am using the right instructions, but I don't seem to have a footrest or an apron. There are levers to adjust a footrest and the cover has a space where a footrest would fit, but there is no solid piece of plastic like I would have expected. Should there be one? Also, does an apron come with it as standard? Thanks for any advice!
