We are looking for a handle set that is similar to your #40-058 but on the outside there is a full oval escutcheon and a more beaver tail lever.
It takes three screws to mount the latch and dead bolt as the dead bolt that is under the lever is attached to a plate that the inside latch mounts over.
It looks to me to be originally supplied from a company called SeasonAll but they are no longer in business, but I could be mistaken.
The customer has no idea on the manufacture of the door.
