Some very old items that have been with me for years. If you work on old cars these might be of use to you.
2 battery terminal connectors, new, 1 is missing the tightening bolt
2 battery post/terminal brushes
2 exhaust system clamps, new
Steering wheel puller
Compression gauge
2 feeler gauges
Spark plug gap tool
Various fuses (some in old containers, which I believe are collectible in themselves)
