internal number This old lamp has been sitting in its box long enough! The internal markings on the filament support show "pibo" on one side and "6325" on the other. From the wording on the box, the bubbles in the outer glass, and the number 6325, my guess is that this lamp was part of lot 63 in 1925.

In case you have trouble reading the descriptive text on the back of the beat-up old box, it says:

The development of the MAZDA lamp for projection purposes has been highly successful and is embodied in the lamp contained in this carton.

This lamp will operate satisfactorily on either direct or alternating current. It has the following advantages: it does not flicker, is clean, requires little attention and is economical in operation. It is noiseless, easily focused and requires adjustment only when first placed in position.

Because of its brilliant and concentrated light source it produces a clear, steady picture when used with the proper optical system.

This lamp is made with the careful attention to quality of workmanship and materials that characterizes all National MAZDA lamps and has popularized their use everywhere.

On the front of the box in large print, it says:


Added in smaller detail it says:


The brass has a heavy patina and the base and filament show no evidence of ever having power applied. The base is tight. The massive filament checks out cold at about 0.7 Ohms, but I have not applied power so it could be gassy. Because of the heavy oxidation, I would not recommend applying power to this lamp without first polishing the brass base! However, if the winning bidder asks, I will apply power briefly to test the seals before we complete the transaction.

Bid high, bid often, and good luck!
