More about this type of keyboard...
The Type II 122-key Model M terminal keyboard was a slight modification over the Type I, simply having underside-accessed flip-out feet instead of side-accessed dual-setting riser-style feet and having a right-angled plastic-jacketed 240-degree pin arranged DIN plug instead of a straight-shaped metal-jacketed one. The front case styling remains the same though, meaning a visual inspection from only the front cannot always distinguish between Type IIs, Type Is or even "F122s". However, a visual inspection from the sides can reveal the difference between a Type II and a Type I or "F122". Type IIs saw use with primarily IBM 3191, 3196, 3197 and 3206 terminals, although they could operate with several others too. Their 24-key function key block could be labelled in either "Cmdxx" or "PFxx" nomenclature like their predecessors.
