Hi Jim,
Since this piece of furniture looks like it served a very specific purpose we will need to reach a wider audience who might know what it is. I was recommended to post these images to an email listserv of museum professionals.

Here is the link to the listserv with instructions to sign up.
Please let me know if you have any difficulties. I would also be happy to sign up and post the images on your behalf.
Posting the images here and on a listserv will hopefully get us some answers about this table.
Thank you.
