Antique Safes/Old Sargent and Greenleaf vault lock


S&G lock
S&G lock  
QUESTION: I have a vault front made by Herring Hall Marvin Safe Co that has a Sargent and Greenleaf 4 wheel combination lock that is missing some parts.  Underneath the name on the inside of the door it has the date of 1933 so I'm guessing the lock is the same vintage. I am guessing a C62 or C64 but the pictures I could find looked different the what I have.  If anything the locking mechanism seems closer to a Diebold design then S&G. Any help would be appreciated so I can begin attempting to track down parts.  Thanks.

ANSWER: Hi Jason,

Your lock is actually a 6810 series lock, which replaced the C62 series (simply a later version).   While Diebold did have a very similar lock, it was never used by HHM.

Sorry, I have to address "vintage" as it is one of my pet peeves about a "misused/abused" word.   Vintage applies to the year of a grape harvest or wine bottling, and NOT old safes or vaults.   The other word I also hate is "patina" as most people using this word have no idea what patina actually is, and are trying to be "antique snobs".    Again, sorry about the pet peeves.

As far as looking for parts for your lock, I really doubt that you are going to find individual parts or pieces, as safe companies do not salvage parts only, and there are no aftermarket companies manufacturing them.   In general, you are going to have to find someone with a full lock to sell you, and then use donor parts from both the lock you have and the one you obtain, to make a functioning lock.    Fortunately you have the dial which will save you a bunch of money.   Cost for a C62 or 6810 series lock in a bronze casing, can easily run around $500, so be prepared to open the piggy bank up!

Unfortunately, the photo of the door is NOT of sufficient resolution for me to look at the handle cam area to see if the rotary bolt is going to be the correct lock for this application.  Please send me a better photo of the door, and specifically the lock / handle cam area.

Note:   A rotary bolt & lever assembly from a C66 or three wheel lock, will not work on a four wheel lock body.

Your other option would be to have a machine shop manufacturer the pieces that you are missing (unless you have these capabilities or skills).   Costs generally run about $100 to $150 per hour plus any material, so finding a replacement lock may be cheaper.

Send an email directly to me stating that you are looking for a C62 or 6810 lock, and I'll look through my parts bins to see what I have.   You can also check with safe companies that are in your area to see if anyone has something.

You can send the request to me at:     

I will be out of the office most of Monday, but the email will remind me to look for the lock to see what I have.

I'm really glad to see that you are interested in restoring your old vault door.

QUESTION: Thanks for the quick reply and the education on "vintage".  I will be sure to share it with others.  Here are two up close pictures of the handle cam area.  Hope they help.

Hi Jason,

As I thought, the C62 series rotary bolt lock is NOT what you are looking for, you would need either the C-64 lock with a sliding bolt, or the 6805 lock with a sliding bolt.

Another option would be a current version of this lock, the SGL 6530-003, gr2 Vault Lock, square bolt, with reversible lever assembly, direct drive.    Cost on the new lock is about $500, plus a dial & dial ring if yours doesn't mate up.

As I mentioned before, send an email request directly to my email, and I'll look to see what locks I might have.
