hardware replacement

A home owner from west Linn, oregon says:
thank you for your help. Our home was built in 1989 and has HURD wood windows. The windows are still intact and I am trying to replace the operating part that no longer is working. Can you help me? I see the number 007900 on the arm. Please let me know if you have a part that will work. thanks, Debby

Hi, Debby.

Your operator looks like an older version of our 39-388 but you'll want to compare our dimensions to yours to confirm everything aligns for what you need.

Thx very much for the help. I'll give it a try before having to replace the entire window :(
