Independent sources and distinct stamp layouts are preserved as individual photographs, not additional main cards. A pictured example alone cannot establish that every lighter from the year used the same construction.

Dating caution. This is a documented period reference, not proof of a precise manufacturing year. Case and insert can have different manufacture dates; inserts may have been replaced. A single feature does not establish authenticity.
