The numbers refer to the reach, rather than the material. It was fairly common for frames to require a longer reach rear brake, so you'll often see a 500 in front and a 730 rear; or a 730 front and an 810 rear. The reason for this is not clear to me; my best guess is it has something to do with horizontal dropouts in which the wheel can move relative to the brake (I know this theory is full of flaws, it's just the best I have).
In the present case, the longer reach front brake is contrary to my expectation and I'd say it's further evidence that the fork has been replaced. But I'm not sure about that. I don't know Cinellis! Note the following:

Try verifying the levelness of the top tube. If the top tube points upwards towards the front, this would again point to a replaced fork.
