This is not a 127 engine, looks to me to be an 850 Saloon (Sedan) engine and it's capacity is probably only 843 cc.
The 127, 903cc engine had the fuel pump mounted on an extended timing chain cover, a spin-on oil filter and a different type of engine mounting bracket above the timing cover etc. The engine shown has a crank pulley with built-in centrifugal oil filter - this was on the 850 but not on the 127.
The 127 engine also rotated clockwise whereas the 843 engines rotated anti-clockwise.
It's possible that the engine could be from an early 850 Coupe/Spider but the 903cc Coupe/Spider engines had a large, finned alloy sump, I'm not sure if the 843cc engine in the early 850 Coupe had a pressed steel sump (as shown in your pics) or the alloy version.
