Tubular National Mazda Lightbulbs

These are National Mazda tubular cage filament lightbulbs. They are very hard to find! These are tipped, so that means they were made before 1922. Tipless bulbs like these do exist, but they can be even harder to find since less were produced (with the tungsten cage filament design).
