An amendment, I did not realize the photo was a segment of a door, again a poor photo, but I now see it is from the Cleveland Fd.so yeas I'm sure i's a triple M.

Here is the video where I captured the photo of the CFR time lock: https://www.flickr.com/photos/canton...57639180762246
Here's a picture of the CRF door (from another thread) with a caption that says the time lock is Sargent & Greenleaf...

I wouldn't put too much stock in the S&G ad. I ran across a different one where the timelock was obviously a Yale. However I have seen the locks on the Fed door and if memory serves they are S&G. The timelock in the video is obviously a 4 movement lock with an attached box on the bottom of the case. That is what we can see. The only assumptions I will make is that the timelock will be the largest available and it certainly looks like a Yale, not a S&G. Based on catalog pictures, only one model fits, the N 4. If it was a medium sized lock it would be an L 4 if one was ever made. The N 4 has a bottom operating connection hence the reason for the attached box. The confusion here is all based on timelocks website showing the M models, and discussion regarding M models with and without the "Open attachment". According to the Yale catalog ALL M models came with the "Open attachment". Now he includes a lock marked "C". It does not have have the "Open attachment". Is it an M? Doubtful but more importantly "M" models do not have a bottom operating connection as do the N and L models. Hopefully this clears things up. Doug
This one has June 12, 1924 stamped on the back:

The caption on the back reads, "THIS GIANT DOOR of a big vault in the Federal Reserve Bank, at Cleveland, is a third larger than any other vault door in the world. Its total weight is 195 tons and it is four feet thick. The delicately adjusted mechanism of the door makes it easy to swing by the pressure of the hand."
and this one has March 30, 1933 stamped on the back (smaller pic size):

I hadn't noticed this before but the CFRs emergency door is to the right of the main door; visible behind the ductwork:

It appears to have been housed in a glass paneled room that is no longer there:

Here's a shot of the ductwork running right up the staircase. I don't recall the old videos mentioning ventilation. It looks low enough where you would need to duck your head when walking under it or else...:(doh):

Do all Federal Reserve Banks have cylindrical type doors like the ones at the Cleveland Fed, Philly Fed, NY Fed, and the PA Treasury?

I show the Philadelphia Fed as having a round door similar to Cleveland:

Other than the NY Fed I believe all other reserve banks have either round or rectangular doors but there are several for which I've never found descriptions and/or imagery.
