I have met an interesting fellow who has a talent to make unavailable tractor parts.  His name is Dan Lehman.  Dan is a great metal worker.  He used the seat back from  Brother John's Oliver 70 and the seat brackets from my Oliver 60 as the sample pieces.  Then, he made a complete Oliver replacement seat that looks original.
Since that first Oliver job, Dan has made other Oliver replacement parts I've needed in my restoration projects.  He has made a baffle plate, another seat, and a pedal lock.
He has been working with metal all of his life.  He received training in his Dad's metal manufacturing shop.  Dan's joy is the challenge in making difficult pieces or no longer available parts.
Dan does fine work and takes pride in his work.  He makes and sells camp grills, rocking chairs, beds, and snowplows for toy tractors, too.
Dan and his wife, Janice, reside in Berne, Indiana.  They have two teenagers, Heath and   Haleigh.
If you have any questions or interest in his work, write or call Dan.  His address is
356 West Wabash,

Berne, Indiana  46711
PH: 219.589.8348         

I recommend him.
