nice bulb, its older than you think. it is from circa 1913-1916 or so. most bulbs made from the 20s on no longer had tips. the transition to tipless lamps using the current exhaustion method began in 1919 and was completed by the early 20s, at least for usa made lamps.

By the way, this specimen is skirted between the envelope and the cap.

Pretty, please no more Chinese failure.
