Does my Thinkpad 10 have a Wacom digitizer?

[sparta.rising]

Recently purchased a Thinkpad 10 second hand. I didn't realize at the time that some models didn't have Wacom digitizers. I did a fresh install of Windows 10 on it, and its not recognizing the pen. Device manager doesn't show any unknown devices and the WinTab driver says the tablet isn't supported. It looks like signs are pointing to this unit not having a Wacom digitizer, but sometimes windows installs a wrong driver and some driver install apps are bad. So is there any definitive way to determine whether it has a digitizer?

If it helps:
Machine Type: 20C3S0KH00

If you have a pen/stylus, is that the official Lenovo one for that model?
Put the original W8.1 back and see if that works.
I wouldn't trust W10 to do anything right...
