I got this years ago to display in my work area, but I do not have enough space. This is a Sears Craftsman timing light, unsure of what year, a guess is 70's or 80's, but that is only a guess. I never tried this tool as I purchased it only for display. This timing light looks to have been fairly well used, it has scratches and pits on the chrome and the paint. This is a neat retro piece. the box is extremely rough, dirty, and torn, the cables are lightly dirty from age/use, it has instructions. A great piece for any collection! If you have any questions, feel free to ask. Opening bid usually wins, so don't be shy.  Selling as is with no returns since it is 40 year old untested tool. Shipping will be 22 dollars in a flat rate box in the US lower 48 only, thank you for looking and have a wonderful day.
