Hope you are able to help or suggest a course of action

We have one of the above which was purchased through Kingsbury Group in Swindon some 15 years ago.
Over the years various bolts etc. have broken and been replaced but we find the foot rest will not stop in there are a number of pull off springs and wonder if some are missing, on the foot rest supports there are 2 pegs with groves which look to take springs but can't find what they would be attached to.
I look forward to your comments
