This was a set 950 ,given to me by a workmate who didnt want it and knowing my lego love felt it'd get a better home. I broke it down found online instructions ,it's blocky and not as stuck together as modern technic. I broke a tiny gearwheel that snapped on inserting the cross pin. It looks awful but for its time must have been a great toy. My friend did say he played the bell out of it
