Could it be one of the Northwest Loaders Madill built in the mid 1970's while designing their 075 loaders , on an early Madill carrier ? BCFP Renfrew Div. ordered and took delivery of a Nortrhwest Loader on a Rubber Tire Carrier in the mid 1970's , I wasn't there at the time , so I'm not sure if the Rubber Tire Carrier was built by Madill . The unit had some issues and was returned to Madill and replaced by the Northwest loader pictured in posting #2419 . The Northwest Loader that was returned to Madill had some upgrades , and then was sold to Pacific Logging Sooke Div. I was running an American 599 loader #561 at Sooke in the Fall / Winter of 1978 , the Northwest was there then .
