Wow, you do not see that too often. Any idea what caused this. Did you check and measure the chain for wear earlier on. You want to make double sure other bits did not get damaged too!

Re: Mercedes W123 240D - Yet another addition to the family
We'll need to retrieve bits of the timing chain from the sump/timing chain tunnel & check for additional damage.
Not sure whether the valves & pistons have undergone significant damage. I intend to rotate the cam shaft by hand, once the timing chain is off, to check for potential damage to the valves. If it rotates freely, we'll probably just leave it as is.
Ditto for the crank shaft/ as well.
Not sure about the exact cause, but I suspect that the timing chain may have jumped off the sprocket (or a few teeth at least). This could have been caused by a limp chain tensioner.
The tensioner seems to be of the type which relies on oil pressure to operate correctly ...
But we'll only know once we take things apart.
I am praying that the damage is only superficial..
