I bought an OC-12 today.  Per the serial number tag the model number is OC12-60D.  Serial Number is 1JX-664.  

   I would appreciate it if someone could tell me how old this crawler is.   I am also wondering who built the diesel engine that oliver used in the model.  The starter has a broken shaft so I am looking for one of those too.    Any help greatly appreciated.   I will try to get some pictures posted soon.
