Check the listing for details. ArcherKit Super Bright Timing Light Kit - Tandy Cat. No. 28-4016. Condition: Used. Listed at 39.99 USD. Wow, look at this! It's an archer timing light kit from 1974! My father's workshop looked like a mini Radio Shack, with all sorts of stuff from the glory days of electronics. But this item really caught my eye. I even found an advertisement for it in Popular Electronics, included in the pictures. It would be the perfect compliment to the ArcherKit Auto Engine Analyzer. C'mon, if you are working on a classic car, wouldn't you want a vintage Tandy timing light kit! The box shows its age, yellowed and having some water and dirt damage, but the parts inside appear to be in good shape. The workshop where it was stored for 40 years was part of a finished basement, so it was never exposed to extreme temperature swings. There is a little greasy feel to some of the parts, but this is to be expected, right? Selling this untested, as is.
