Vintage G.E. Automotive Miniature Lamps No. 51, automobilia

Package of 10 vintage automotive instrument indicator light bulbs, No. 51. Made by General Electric in the U.S.A. The graphics on the box are nice for a vintage display. I’m not sure of the age, I’m guessing 40s or 50s. Box is in good condition, with corner scraping and some pen scribbling on the back. Two of the bulbs have blackened tops. The filaments look intact, but maybe they were used. From a smoke free and pet free home.
