Hello all, I recently found a mason jar lid with the CFJCo ( Consolidated Fruit Jar Company) monogram glass insert. My question is how long was this style lid used for and what time period? From the searching I have done it seems that it may be from 1880-1890? Was hoping someone had more insight on the date range of the glass insert mason jar lid. The embossing on the insert reads: REGISTERED TRADEMARK MASONS IMPROVED 1871,23 MAY.
Any insight is appreciated!
