As far as I can recall the number of the crankcase is four figure - 6XXX so presumably quite early which I think was the rationale for obtaining it in the first place. I'm certainly not set on using it if I can find another earlyish crankcase in reasonable condition.
To my untrained eye, I would guess that the damage is from it being dropped/having something dropped on it while out the car, rather than as a result of an engine failure, but I may well be wrong.
