This is an NOS 6V GE #4030 headlight bulb.  It has no alignment tips and was made in the mid 1950's prior to the headlight bulbs having the three alignment tips raised in the face of the glass. The bulb measures 7" in diameter and has the large fluting in the glass.   The bulb has "Sealed Beam....GE....Made in USA" raised in the glass at the bottom. It was tested and in perfect working condition on HI and LO beams.   These GE bulbs  are documented in the CTCI Restoration Manual for authenticity.   See my eBay Store for more NOS 6V and 12V headlight bulbs.  We charge actual shipping only and are always glad to combine shipping on several auctions or you would be welcome to pick them up at our shop. Thanks!
