No standard Chubb part number Ive ever seen. The other numbers being internal part numbers / contract numbers etc.

I'm sure others will no more. They are nicely made locks.
Thanks, oldlock, they are a very tactile and interesting little padlock.
Interesting that they would have a keyway drop on one but not the other. Very nicely made and been around for quite some time going by the dates on the back of them.
