Hand Blender Parts (Boscombe East BH7)

A bit of a long shot but here goes. We have 2 hand blenders also known as stick blenders. Both are not working. The one of the right (all plastic) has a working top part (motor part) but unfortunately the guard round the blade has broken off and so is dangerous to use. Does anyone have the lower part to this hand blender that they no longer use/need? It is unbranded but has the number 589 126 written on the label. The problem with the other hand blender is the other way round. The bottom, metal part, is fine but the top part with the motor isn't working. So does anyone have the motor part of this hand blender that they no longer want? This is a Tesco model HB09. Unfortunately, the two parts of these blenders are not interchangeable. Failing the above, does anyone have a complete, working hand blender that they no longer need? Thanks for your consideration.
