After I purchased a scale model of the Oliver HG , a pair of real Oliver HG&#039;scame my way...One is a narrow track and the other is wide. Both run well and use magnetos for ignition. 
I have not been able to find informaiton on this model on the websites listed for Oliver.
A parts book and a manual is needed. Also a pair of fenders and one grill.
Are these parts shared by any other Oliver or Cletrac machines?
thank you
Verne
