Well this has been a subject on the wet-plate boards as well. Tim Merrite still makes the top half (the head brace part) but not the bottoms any longer. I think that’s who your talking about in your post.
What some have suggested is that you purchase the top from Tim and but a modern cast “victorian” style table bottom (just google it) and adapt it to the top.
I will be going this route as a summer project. I’ll keep you posted
