Herring-Hall-Marvin Safe Co.floor safe

I just picked up one of these for FREE. I have the combination, works. It has a flat plate door behind the main door and has a place for a key. Then there’s a little door up in the left hand corner and the lock set is missing. I would like to get the little lockset for the little compartment. I would also like to get one of the caps that go on the top and bottom of the hinges. I think there just for appearance. Does anyone have any info or parts for these safes. Thanks
