Help with dating a Corbin cabinet lock

[PBcrackers]

Hi all, I found this forum while trying to find more information, specifically a date for a lock I have on an old medical cabinet. I've been trying to date this cabinet and an almost idental one I have through the hardware on each as any other method has been unsuccessful. The designs are so similar to the companies that made them years back and very little is available online as far as old catalogs digitized or any write ups about them. So having said that my last resort is the lock on one that I found a name on and a number. I'm not sure what this lock is called....figured it was a "cabinet" lock since it's on a cabinet but I don't really know. The lock part itself is gone and I'd like to replace it if possible on this cabinet. The other cabinet...same lock/mechanism but rusted over so I can't read any numbers but I'm sure it's the same lock. No key for either cabinet of course :(. It has a 1WG and then 8 on the lock.

TIA!
