McCobb / Connoisseur Coll. Dry Bar  

Locks
I did say that I was theorizing, didn't I?
It's interesting that your dry bar has a different lock from the one we displayed at NYC 20.
The lock on your chest is consistent with Directional production post 1957, specifically it is consistent with the locks used on the McCobb Living Wall units produced after 1959 which were also produced by H. Sacks and Sons.
This just might give greater credence to the chance that locks on the dry bars were optional after a certain point in production.
