Both the other threads and the 2 photos are the Corliss, if you now want info on the vault door then clear photos plus close-ups are essential.
There are often many unknowns and surprises involved with the old doors when missing parts. My advice would be to use someone as local as possible in order to make the project work effectively.
Without knowing the condition of wear and without seeing the door and taking specific dimensions, it’d be wishful thinking that anyone can make parts that will fit perfectly. If you use a local specialist they can measure and assess everything accurately from the actual door, and call by whenever they need in order to make checks and offer up parts in progress etc. I once made a load of 2 inch diameter vault locking bolts with the slots cut to fit the tail bars, all drilled and tapped old British imperial threads etc, done for another locksmith going by his dimensions from site. It turned out he didn’t measure the actual big Milners door they were missing from, he measured one of three similar doors in the basement and guess what- they were different!
Will be a nice project for someone, and All down to condition of the door, and what’s there and what isn’t really.
