Vintage Industrial Westinghouse SAH-250B 250W 42V Mercury Vapor Light Bulb

This is a westinghouse sah-250b light bulb. This is an industrial light bulb, and I have no way to test it. It is sold as is untested. The bottom part by the socket is cracked, and there is a loose chip floating around in the bottom section of the bulb. I do not know if this works. This bulb comes exactly as I found it, in the box with foam. Please note the box says ng, which could mean no good. This was from a large lot of machinist measuring tools, and this was one thing that came in the box. This is untested, and is sold as is with no returns. Please bid assuming it is broken, as I think it is, even though I can not test it. Please look at pictures closely. I combine shipping so be sure to check my other items. Shipping is to continental U.S. only. Posted with eBay Mobile
