- Greetings All!
To assist in building an On3 Puffing Billy R'way NRT-1, a 4 wheel
rail tractor named "William A Collis"
I need two major dimensions.
(a) The wheel diameter actual.
(b) The distance between the axle centres actual.
Stefan Rebgetz has 100+ photographs in his NRT1 album:
It is planned to construct the body from etched brass and power the
NRT-1 with an appropriate mechanism.
I hope that someone from this list could help me with dimensions.
