Unitron 75 MM refactor

Have a Unitron 75mm refractor. The colimation adjustment on the lens appears as though there is something missing. On other refractors I have had it the whole cell would adjust. On this unitron it looks like it is the main ring that holds the lens in place that is adjusting and it looks like it is tilting the lens in the cell. If I shake the tube the lens rattles inside the lens. This cannot be right. Am I missing something of this lens assembly?????
