From the July 15, 1903 issue of American Carbonator and American Bottler:
Here are a few of the endorsements that appear with the advertisement:
Gentlemen:–Enclosed you will fid a check to pay for the Cork Extracting Machine we purchased from you. We risk to say that we are entirely satisfied with every respect. It fulfills every requirement and renders accident from broken bottles almost an impossibility.
Burkhardt Brewing Co.
Thomas J. Sproul, Treas
Dear Sirs:–We have used you National Corkpuller for several months and it is great labor-saving device. It pulls the cork quicker, and more easy than the old style way. It saves serious damage to our bottlers who drew the corks by hand and in many instances the heads would break and lacerate their hands, whereas the corkpuller saves all accidents and liability to the employer.
Frank M Doyle
186 Commercial St.
Gentlemen:–The National Cork Extractor that you sold to us, we have found to come up to our expectation and we would be unable to get along without it in our bottling establishment.
You can use our name in recommending it to anybody, as to us it fills a long felt want in the bottling business.
Beret & Co.
