Need deadbolt for metal security door

I'm afraid your images didn't come through. Could you try uploading them again for me?

Thanks for resubmitting your pictures. Look at our 40-119 security door mortise lock set. I think this is our best match. You might need to switch the latch around for a left or right hand swing door. If you are unable to do so, you might need the help of a locksmith to switch the hand.

I'm not sure if they still have one exactly like yours. That said, you should be able to reuse your existing inside thumb turn. You may want to check with a local locksmith, as well.
