What Kuhn model is the John Deerre 1460 cutter bar?

I have a John Deere 1460 discbine and I have broken two turtle shells.  Good ole John Deere gets just under $300 a piece for them.  I know Kuhn made the cutter bar for Deere.  In fact the the turtle shell I picked up Saturday at the Milan IL warehouse was red thus a Kuhn.  I am sure some knowledgable folks here know what Kuhn mode; uses the same part.

 

Thanks,

Bill
