"seeing that the HS compartment is missing and the bit at te top under the TP is bent upwards I can't see that the screw jack is present, could you please identify post(s) where it can be seen. Ta"
The compartment is not missing at all. The entire upper part is present, including the jackscrew. What is missing is the 2 struts that support the hinge assy of the HS and the HS itself (less the snapped off part already found.)
Will take a while, but will find the photo for you. With all the post numbers being jumbled by the censors, all my linked numbers are no good.
