I'm sorry to hear they're not the same. Can you go into more detail why? What exactly was the difference?
Knowing when the house was built doesn't help. The only way to identify this hardware is through comparing its physical attributes. If you tell me how they differ, we will do our best to find a match.
Perhaps it would be best to order them again and see if they will fit. I just eyeballed it before. I hope they will work!
