Hey Oliver1,
Thanks for the help on the ID of the Oliver threshing machine for me, it was greatly appreciated.  My dad and I were just curious on the year that it was and some info on it.  Do you by chance know how much a thresher like that is worth?  Just a round about number.  We aren't looking to get rid of it as it's a part of my grandfathers collection along with an old steam engine and oil pull.
Anyhow, Thanks again for the help.
Steve
