Antique MASON Jar RARE Intertwined Monogram ERROR Mold Transition \"SWG\" with Q For Sale

This Antique MASON Jar is an Extremely RARE Intertwined Monogram ERROR Mold Transition \"SWG\" with \"Q\" Logo inside. The \"SWG\" stands for Southwest Glass Mfg. Co. and the \"Q\" inside represents the Quartz Glass & Mfg. Co. Southwest Glass Manufacturing Company produced highly collectible fruit jars for a very short window between 1903 and 1904. In late 1906 or early 1907 Southwest Glass was bought out and morphedinto the Quartz Glass and Manufacturing Company. Rather than casting new iron molds the factory took the existing \"SWG\" monogram Molds and altered them to incorporate a \"Q\" for (Quartz Glass), resulting in the overlapping \"SWG/QG\" design you see. This jar is so rare, I couldn\'t find any sold or active listings anywhere on the internet, including !

This MASON jar has natural pink manganese tint and comes with the original Ball zinc lid. There are air bubbles through out and a large air bubble over the top of the \"A\" in MASON. It was difficult to photograph the Logo so I used different lighting and have information pics for what the Logo looks like. Please see pics for best description and condition! I will ship U.S.P.S. and purchase extra insurance, and require signature conformation. Thanks for reading!
