This antique timing strobe light was manufactured by the Frank N. Wood Company of Waukesha, Wisconsin.  I have no idea if it works, nor of the era of its manufacture, though I'd guess the 1950s or 60s.  The decals on it are starting to peel, but other than a bit of dirt on the case it's in great shape. The lens is intact and the cables are nice as well.
Please ask me if you'd like additional photos.  I don't know the history or the frequency of use of this tool, so it's sold as-is, no returns. I'll pack this REALLY carefully so it arrives intact.

Thank you for looking and have a great day.
