I didn't know that. I figured the webcam was removed since the 2nd batch X210s had them.[1] It looks like the 2nd batch chassis is the X201, not the X201s.
If you want to see (most) of the many "TYPE xxxx-xxx" variants of a given older ThinkPad model number, and don't mind doing some detective work, you can Google for "PSREF" PDF files.
The PSREFs were/are catalogs of the variants available for sale and their specs, issued periodically. There were also PSREFs for withdrawn variants, covering year ranges.
(I got well-acquainted with these when stockpiling X200 units for Coreboot, a large-screen workstation model I like, and an older model that has better build-quality keyboards that can be swapped into certain newer models.)
Various Lenovo Web site lookups of specs have come and gone, and TYPEs seem to disappear from them sometimes, but the PSREF PDFs are forever.
Sorry I don't seem to have PSREFs covering X210S, but I suspect they're out there.
