As we go on digs around the world, we get to piece together a history on the optical industry. Just as we think we know, we learn that there is always more knowledge to gather. I was schooled on a buy this past week from the original Optyl rep from 1977-1984 about many things. The coolest was his Boeing Carrera Salesman case, that yes, we did purchase, with every single Boeing Carrera Frame ever made! Sick!
