Hi all!  We are new to the oliver family and looking for some help.  My nephew just bought 2 Oliver 60&quot;s.  One has a widefront and the ser.# has a B at the end.  What does that mean?  Is it a desirable tractor?  

Also he is in need for some good tin, hood, side curtins and belt pulley.  Can you folks help us out and direct us to some parts?

Thanks for your help!
