THATCHER 1941 & 1942 CALENDAR MILK BOTTLES

Finding 1941 & 1942 Thatcher round calendar milk bottles offered for sale can be difficult to do. Most of them were professionally painted inside to be used as display bottles for customers. These two bottles were never sent away for inside painting for some reason. This 1942 example has black months just like the 1941 example. The 1942 examples that are seen painted inside has blue month calendars. Any milk collectors who could share thoughts or information on these bottles would be appreciated. They are quite rare & even more difficult than the inside painted ones.
