Vintage HK GERMANY 12V light bulb box

Blue painted HK reserve bulb box in used condition. The box is made of metal, rusty, with patina and stamped with “HK Autolampen Sicherungen which is translated “bulb fuse light box”. The box has the original first color, the top cover is dent free, the open close function is ok and the inlay inside is a bit aged. The replacement bulb box is 15 cm width, 5 cm depth and 11 cm height and was made in Germany by HK in the 60ies. I had a look at the big bulbs and they are for 12V but I did not check the small bulbs.
