wife and myself were given a gift of a WIDDOP carriage clock, when I went to change the battery I found the battery compartment loose resulting in the battery holder and the clock hands moving freely, I have noticed the nut on the clock face holding the battery compartment in place is loose, it is on the spindle, behind the pointers, unfortunately I cannot find out how to access the nut or clock face as I cannot see without using force, how to open the case, I did contact Widdop and the young lady was prompt with her reply promising to find out for me but that was well over a week ago, can anybody here help please on how to access the clock face so I can tighten the nut, all help and advice appreciated, thanks
