With reference to post#69 when I raised this very point with Wanni, he raised some side issues that are relevant to this discussion.
1. He ( Wanni ) stated that he has around seven or eight clients who may each purchase anything from ten to twentyfive units ( Transaxles) per annum. This means his annual production could be anything from 70 to 200 , and as he has around five different models if not more the actual volume of parts is relatively small.
2. In that #69 post if I read it correctly he made the offer to anyone to purchase the rights to one of the obsolete models should they wish to produce it.
3. He states that he doesnt wish to do so himself for the simple reason he doesnt need phone calls from all corners of the globe because Jimi Whatsit has fitted this trans to his 1959 Goggomobile & decided in his wisdom to use recycled sperm whale oil & cannot get second on a quick downshift.--sorry, but I am sure you know what I mean.
While Eric states that current purpose built transaxles are expensive due to the limited numbers, this gets away from the point of building a transaxle using currently available off the shelf components from volume produced gearbox & or rear axle assys. There is or should be no need to even consider getting special R&P sets cut or machined. At most all that is need is a couple of shafts and a set of housings in which to install the parts. This is not going to be a demon lightweight /just strong enough to do the job/ specialist reqd to assemble type effort-- It would be a tough-simple-4 or 5 speed H pattern shift trans based on USA basics. Why use Porsche or other semi exotics as a basis when the core prices are so high & indeed if you have to buy new parts to overhaul them its often less expensive to buy another SH trans & hope its OK. I believe this would satisfy 80/90% of replica builders of GT40 & T70 type cars. The guys who want sequential/paddle shift etc would just have to pay the extra for their dreams.
