The "Key hole" is for the winter curtain that goes in front of the radiator.
A chain is routed through the hole (like the one used to secure the plug for your sink) and can be used to raise and lower the curtain.
This hole for the winter curtain: Is this original or is it some later modification? The reason i ask is that i have the same on my MB-45
It is a later modification done by the Norwegian Army.
