Door handle

Thanks for posting. The 82-107 Thumb Lever can likely work as a substitute, but I am afraid it only comes in white. You could also consider all-new handle sets: see our 82-089 or 82-090, depending on the finish you prefer. Note too that there's a chance the thumb lever broke due to the mortise lock it interacts with being broken. To test this, remove the handle set from the door and try manually 'throwing' the lock with a slotted screwdriver. If it doesn't budge, then you know the lock needs to be replaced as well. 

Thanks for posting. I'm afraid we don't have handle sets like this with a base plate that long, but keep in mind that won't affect compatibility with your door in any way. What matters is the hole spacing, or the distance between the center of each mounting hole. So long as the hole spacing is 3-15/16", then the 82-089 or 82-090 would work for you.
