1914 Mosler Strong room? Vault?door

[Doug MacQueen]

I hate to disagree with Huw, but I must. Your post is overly complicated with way too many extraneous pictures. Adding pictures of other doors, which are not the same as yours is not helpful. Anyway so you are looking for a lock and your door is left hand. Yale/ Mosler flipper or friction fence locks will work with either hand door. Since I don't pay a whole lot of attention to models numbers, let's use dimensions and pictures instead. I am sending a picture of an incomplete lock as a starting point. Also important measurement is door thickness but it looks like yours is about 1/2" with another 1/2" mounting plate,. so the mounted tube that goes through the large hole should not be so difficult to find. This lock does not have the tube mounted and I am not sure I have it or any tube for that matter. Most tubes will be longer and cut to fit. The 3 smaller holes are for 1. Tapped hole for bolt backup stop bolt. 2. Untapped hole for pin sticking out back of lock. 3 Tapped hole for case mounting screw. Not sure why this one was there as the tube mounted lock versions did not use the case screws. Pictures to follow.

Not really, just surprised at your impatience.
