I found the answer I was seeking in a deleted post which I hadn't noticed 'til just now. Thanks to @todd-smith for the animated gif in this deleted post https://scifi.stackexchange.com/a/262622/31181

• showing the linkages which produce the prop motions
• accurately reproducing the movement of the original prop

I'd like to give him credit for the find if possible.
