Hi Mike,
    If you ned pulleys and parts, you can try Larry Harsin, he is at <!-- w --><a class="postlink" href="http://www.olivermechanic.com">www.olivermechanic.com</a><!-- w --> (I have phone # somewhere around here, but can't find it at the moment) He has many parts ....if not what you are looking for at least he can point you in the right direction. He may also have the side curtins you want.
 Oliver Schaefer may have stuff also, I have not dealt with him, but I have seen his ads...it would be worth a look at    <!-- w --><a class="postlink" href="http://www.ollieoliver.com">www.ollieoliver.com</a><!-- w -->
   Steiner Tractor Parts offers reproduction side curtins and parts at  <!-- w --><a class="postlink" href="http://www.steinertractor.com">www.steinertractor.com</a><!-- w -->
   Sorry I cannot help you with the serial #, but perhaps John Schweibert or Chris Losey can ( I have enough trouble figuring out what day it is <!-- s:roll: --><img src="{SMILIES_PATH}/icon_rolleyes.gif" alt=":roll:" title="Rolling Eyes" /><!-- s:roll: --> )
 Hope this is a start for you,
                Cal Innes
