Tom,
     Before you make any assumptions about the crank-arms being damaged, consider first the response sent by Chuck Brooks. Also, if you read nothing else in my message, please read the comments I have hear the end...
     So, in my experience, the number on earlier Campagnolo spindles relates to the over-lock-nut dimension of the rear wheel and, therefore indirectly, the chainline. (On later Campagnolo spindles, the number related to the width of the BB shell.) The earliest Campy track hubs were for frames with 110mm spacing at the rear and crank spindles were about 105mm long.
     Here's why I think your whole situation is a bit confusing: those shorter spindle were meant for frames with narrower bottom bracket shells than the 68mm shell that I suspect is on your Raleigh. But my recollection is that those shorter spindles were meant to be used with thin-wall cups. So I wouldn't be surprised if, the reason this thing even fits on your frame at all right now, is that you're using thick wall (i.e. NR) cups. Otherwise, the adjustable cup would be too far into the frame to accept a lock ring.
     Does that sound reasonable? If not, please let me know, because I'd be interested in learning what the true story would be.
