Basically I need to know if Oliver offered an optional rollbar and sunshade top for the 1855. I'd like to find one to work into my restoration as an upgrade. I also need to know where to get the correct type seat. The cushions on the back and bottom are completely gone. What is left appears to have been black but the only NOS one I have seen was white. What is the correct color? This is suppose to be a 1970 year model.
