|The oldest published design I found yet was from Mr. M.J. Oliver, printed in The Meccano Magazine, Jan 1957. It is based on the description given two years earlier by Mr. Cousins|
|Twenty (!) years later, in 1977, Mr. Terry Morris revived the previous design in
another article in The Meccano Magazine.
Apart from more stylish wheels this model adds little new insight.
|But it sparked new interest, e.g. the (undated) model from Ashok Banerjee.|
|Even today new models are built using the classic screw&bolt parts, like this wonderful specimen of Hans-Gerd Finke.|

|And finally ths LEGO contraption, build by Philipp Hörler. Basic design seems to be simular to "my" ODTS II|
|Did I say "finally"? Some guy in Taiwan (sorry, I couldn't decode his Chinese homepage) built this LEGO model - aesthetically most pleasing! I stole his instruction sheets, see here, here and here for the benefit of other "westerners".|

great concept: Planetary Gears for the differential! For some theory
