...and it's certainly an interesting story that goes your little piece of printing plate. A little more on that...
A flipped image of your posted pic. The Serial Number 421 would have been issued by the Gov't to the manufacturer of the product and with a little more digging you could probably find a name to go with it :

A Coca-Cola ad from 1907 displaying the guarantee along with their issued Serial Number:
Here's the skinny on the Guarantee and the Serial Number from the link below. Interesting find, Tim, thanks for posting!
>>>Congress had intended the provision (The Pure Food & Drugs Act) to protect retailers from prosecution if they unwittingly sold products that failed to meet the requirements of the law. To avoid prosecution, retailers needed only to
present a guarantee from the wholesaler, jobber, or manufacturer, who then
would be held responsible for any violation of the law.
Administrative regulations, including food inspection decision 40,
permitted retail firms to file a general guarantee with the Bureau of
Chemistry. Once filed, the firm could display the guarantee on their label.
It would read, "Guaranteed by the Food and Drug Act of 1906, guarantee
number ," with the number being issued by the Bureau of Chemistry.
This display of the guarantee on the label went beyond the meaning of the law; it gave the impression that the government guaranteed the purity of the
product to the consumer [26, 15]....
...As consumers began to use guarantees as a guide, firms found them
commercially valuable. This tended to favor goods that were shipped in
interstate commerce over local products. Interstate shipments were subject
to the Pure Food Act and thus could use the guarantee on their label; local
shipments could not. It also favored domestic goods over imports, because
foreign manufacturers could not be granted a guarantee [23].....
...One the most blatant abusers of the guarantee clause was Sunny Brook,
a distiller of straight whiskey. They launched an advertising campaign that
claimed that their product had the official approval of government inspectors.
Advertisements and billboards showed Sunny Brook with an official looking
document called the "National Pure Food Law." The wording proclaimed
Sunny Brook was "The Pure Food Whiskey." Other advertisements showed
a man in an official looking uniform with "U.S." displayed on the lapels and
"Inspector" on the cap. He held bottles of Sunny Brook, or else signed the
label which said, "Ok, U.S. Pure Food Inspectors." The label on the bottle
read "Sunny Brook Whiskey, Bottled in Bond, Age and Purity--Proof and
Measure Guaranteed by U.S. Government."<<<
