Pictured is the MB110LL/B.
From Wikipedia
It is worth noting that there are two versions of the A1243 keyboard (the MB110LL/A and MB110LL/B), that are distinguished by the icons on the F3 and F4 keys. This slight update took place in July 2011 on the release of OS X Lion and changed the label on the Exposékey (F3) to Mission Control and changing the Dashboard key (F4) to a Launchpad key.
Will this keyboard still be supported by Tahoe (macOS 26)? Quien sabe.
