In followup to my last post, I'll get more specific about the key numbers.
Canada Post just installed a new rack of mail delivery boxes at our brand new townhouse complex.
There are 15 mail boxes in the rack, and I recorded the number stamped on the back of each key latch before they closed it up.
Each number was in the form: 40xxAF, where xx was a two digit number ranging from 15 to 30.
My key is marked "National Cabinet Lock: Made in USA".
Is there any other information can be gleaned from this?
Thanks!
