John Sheerin was a native of Ireland, and named the company Shamrock Oil and Gas after the symbol of his country of origin. This Shamrock Trail Master porcelain pump plate dates from the 1950s and measures 12.5 inches tall by 10.5 inches wide. It features five of the six original grommets around the outer edge and a nice clean glossy field. Some small chips can be seen around the the bottom edge, and some touchup is noticeable around the two bottom grommets, the left middle, and the upper right. Some light discoloration can be seen on the bottom, along with some some faint spider web marks on the lower right. Just a great porcelain pump plate that won’t break the bank! 20556-ETP
