Hi Rob,
If it is an electrolytic it would definitely have either a + at one end or have one end coloured red. Maybe both of these things. However, if there was a case marking it could have become rubbed off. You could always sit under a strong light and try breathing on the case to see if there's any signs of old marks?
If it is a non electrolytic cap I'd suggest replacing with a 1000vdc component to be on the safe side, if the voltage rating is unknown.
It is interesting to see it was mounted in a clamp. I have only ever seen electrolytic capacitors mounted this way and it appears to be far larger than a typical non electrolytic cap.
