Fitting a Jena Tessar 21cm 210cm in a Linhof board

[korby]

I'm looking to get a Jena Tessar 210mm 4.5 fitted on a Linhof board for my Shen Hao 4x5.
I ran across this on ebay (https://www.ebay.com/itm/Carl-Zeiss-Jena-Tessar-21cm-210mm-f-4-5-f-4-5-Lens-w-Copal-No-3-Shutter-382935/163639721466). I asked the seller what is needed to fit this on a Linhof board, and the reply was a "ring" and a "board with screws", but I'm not familiar with "screws".
Could someone please point me in the right direction or reply with a link with such "screws"?
As you can tell, I'm relatively new to this. I already got another lens, but it was neatly fitted on a board and ready to shoot.

Thanks!

SK Grimes does great lens mounting.
Check skgrimes.com, and follow the "lens mounting" link.

You need a board cut for a Copal 3 shutter and a retaining ring

Hmm. Ring and board with screws make me think flange. See skgrimes.com for an explanation.

Flange makes me wonder whether the lens is in shutter. If it is not in shutter, it will be difficulty to use on a camera without a focal plane shutter. That's your Shen.
