Hello all. I have recently purchased a 1968 Thunderbird clock. It is an original nos product and came in the original box(very cool!!) I hooked up power and it worked great but I cannot adjust the hour, minute or second hands to the appropriate time. There is a/an metal rod at the bottom of the assembly but when I try to pull it out or push it in it does not adjust the hands. Any help would be greatly appreciated. Thank you.
