I'm looking for information on a loader that is on a oc-3 i just bought. The tag says Greenville steel car company from Ca. Already talked to Landis with a little bit of info. Looking for more info if possible because it has a feature that was later patented by Ware. No track springs(subframe). And also has hidden hydraulic res. and the rear ripper operates off rollback of bucket. Wondering if anyone has any knowledge of these loaders and possibly any sales info. This loader is on an early oc3 (1951) #36. Thanks for any help.
