One way to determine whether or not hand painted/stenciled bottles exist is to try and figure out when the first stenciling machines became common. Even for the big glass makers like Owens-Illinois and Thatcher, I have to believe the introduction of stenciling machines was a gradual process and didn't occur overnight - just as the transition from fully embossed bottles to ACLs was a gradual process for the bottlers who used them.
Take for example the following machines - which were invented by individuals listed as "Assignors" to the Owens-Illinois Glass Company. I'm still searching for earlier examples because it appears that by the time these two machines were invented the ACL process had advanced considerably. But even with that said, they give us a peek at what was going on at the time, and might provide clues to earlier bottle stenciling machines.
This first example was ...
Filed for in 1938
Granted in 1941
[ Notice the label in this cropped portion - and that it appears to be a beverage bottle ]
This next example was ...
Filed for in 1941
Granted in 1942
I especially like this one because its the earliest I could find that addressed the shoulder ACL application.

The image below is cropped from the 1939 Julian Toulouse article. Notice that none of the ACLs pictured have a shoulder ACL. Now I'm wondering when the first/earliest shoulder ACLs were produced.
You're the 7up guy among us - when did the ACL shoulder emblems first appear on 7up bottles? I'm thinking around 1938, but I'm not certain. If the shoulder ACLs did start around 1938, they might tie-in with the 1941-1942 shoulder stenciling machine I just posted.
