What is the Dell Keyboard part number for the Operator workstations?  I am looking to buy some keyboard skin protectors to facilitate the frequent hygiene cleaning requirements during this COVID-19 situation.  I found "Keyboard Cover Skin Protector for Dell KB212-B / KB4021".  Does anyone know what gets shipped?  I looked at last year's version upgrade quotes and there is no mention of keyboard but we all know a keyboard is always included, nowadays, with any new workstation that is ordered.  And if anyone knows where to get these keyboard protectors, please to do share.  

Thanks,

Raúl
