David Howe has confirmed my suspicions: the Austin factory produced the Sports front axle from a standard forging, hence they have 1A numbers forged on them; they 'stretched' them in the re-forging process so that they are the same length as the standard axle. The axles were then stamped with 9C numbers for Ulsters and 9E for later Nippy etc. The cross tube levers and steering arm have 9C numbers forged in on Ulsters and the cranked down cross tube levers are keyed into the stub axles to prevent twisting.
On the Ulster the springs were produced outside the factory and stamped with 9C numbers on both S/C and un-S/C Ulsters. Parts common to the S/C cars and un-S/C cars always had 9C numbers, parts for the un-S/C car, like the cylinder head, had 9E numbers.
