More on this type of keyboard...
The IBM 3727 Operator Console was the operator console designed for the IBM 3725 Communication Controller that was announced alongside it in 1983. The IBM 3725 was intended for IBM System/370 and compatible (303X and 4300 series) processors and could be used to facilitate communication between up to 6 IBM host processors locally or provide up to 256 line attachments at a remote location. Compared to previous 3700 family communication controllers, the 3727 was required to operate and utilise the enhanced system management functions that were an integral component of the 3725. They were used as part of the 3725's Maintenance and Operator Subsystem (MOSS) where a primary and alternate remote operator console could be attached. Furthermore, via the IBM 7427 Console Switching Unit, those 3727s could be switched between four (primary console) or six (alternate remote console) 3725s.
The 3727 Operator Console Keyboard (type "310X" as per their rear labels) was an 87-key keyboard that heavily resembled the earlier IBM 3101 ASCII Display Terminal Keyboard but can be easily distinguished by the 3727 keyboard's lack of DIP switches above the keys. The keyboard was only known to have a US English ASCII style layout that could also be quickly distinguished from the 3101's layout by the 3 black keys that were mechanically locked and its 8 program function ("SELN AREA", "CCU FNCTN", "MSG" and PF1 through PF5) keys taking up the left-side 4x2 key bank.
The 3727 keyboard had a black cable terminating in a female DA-15 plug. Like the 3101 keyboard, the 3727 keyboard was unique amongst Model B keyboards for having branding in the form of a rectangular silver "IBM" badge. In May 1983, the 3727 keyboard cost $420 USD or ~$1,234 as of 2022 (adjusted for inflation).
