Jason,
Contact the Floyd County Historical Society in Charles City, IA.  I have purchased some Oliver sales videos showing new equipment demonstrated in the field from there and enjoyed them.  I don&#039;t have contact info handy, but you should easily be able to locate them by doing a search on the web.  They also advertise in the HPOCA mag.  They also have original operators, shop, and parts manuals.  Good luck, dwm
