Robert, I fail to see the "blue chip stock" connection with Parker Brothers guns. Old ads in my collection indicate that graded Parkers were being offered for sale at severely discounted prices on the used gun market and Parker Brothers was sending them out to dealers several times before they finally "stuck" and were successfully marketed at the retail level. The manufacture and sale of new graded Parkers was very abbreviated in the Depression era. By the way, Parker order books with any substance ended in 1919. The mention of Emil Flues in books I have examined were apparently 1919 and before. Another gunsmith of renown mentioned in the Parker order books was Frank Novotny. Of course, Fox trigger inventor Joseph Kautsky was mentioned based on the fact that he was in the retail gun business and ordered Parkers for his store.
