Need help Identifying surface book model (unable to turn on)

I have a client's Surface Book (he says its a SB2) in my possession. I am replacing the screen.

SN I used on bottom of tablet is 008835472357
SN on bottom of keyboard is 027363772854

On the hinge where the keyboard is located, it says Model: 1785

When I run the SN for the tablet, it comes back as:
Surface Book - 512GB i7 16GB with Performance Base

The screen that came off the system is listed as PN:
X905082-016

I ordered another screen, and it's part number is:
X905082-012

I cannot find any information on the difference in the screens (if any), and I can't confirm it's a Surface Book 2. The iFixit screen they have for the Surface Book 1 and 2 for the 13.5" model is (at least in pictures) X905082-011, and all the Surface Book 2 models are 18XX, and the Surface Book models are all 17XX (including the 1785)

Can anyone assist here?
