I have designed motorcycle parts that I had 3D printed to verify geometry on the bike before spending the money on machining. I believe it is also possible to 3D print a casting pattern, probably the approach that Colin's casting company was planning to use. It isn't cheap for something that size, probably well over $1000 and a full day on the printer. If they can't get a decent scan you could have the part modelled in 3D CAD and print a pattern from that. You would have to estimate the missing surfaces so it might not be 100% original, but in this case I dare say you'll never get called out on it. The only design constraint would be that it not hit the floor on the outside or the gears on the inside.
