Somewhere there must be multiple incomplete lenses that could be digitized and digitally combined to make complete unit. No working unit should be broken to get the model. I have reached out to those I know that might have carcasses. I have not been successful to acquire the remnants. I am even willing to pay for the broken parts to get this project going. The track guys may also have them somewhere. In the old forum, we could create polls or surveys. If we could ennumerate the need, we might get a better response to this project.
