I don't believe you will find anyone. I have the same deck and have looked for years with no luck. I have resorted to using friends in machine shops to repilcate some parts for me. The bearings and seals in the gear box can be matched up to common stuff at your local bearing house. What parts are you looking for? Is this a 3 point mount or belly mount? Mine is a 3 point 52" finish mower, left hand discharge. Last set of blades I purchased came from Stuu Equip in Pgh. PA.
If you need any more info, let me know.
