one in solder and the other in wax, they look similar to conduit bushings:







1966. A listening device for finding defects in machines, motors, dynamos, or turbines, the instructions state:

...fix the end of the device (when needed mount the extension pieces together) on the external part of the examined surface such as a cylinder, gearbox, carb, differential, mechanical parts, pipes and so on. Put the membrane to your ear and diagnose by simply listening for defects such as oil deficiency, loose bolts or screws, etc. In danger of electrocution use the red insulated sound finder that neutralizes electricity. When checking for pipe defects hold the device to the raised examinated part such as hydrants. It will work even through brick walls, bitumen and soil to diagnose the defect.

2015. These are hydrogen fuel cells, supposedly they will increase your fuel mileage up to 60%. The seller states:

Turn water into hydrogen gas with electrolysis. Hydrogen's octane is 137% and can be burned in your engine with your gasoline or diesel fuel. This has many positive effects on your vehicle and the environment. When you burn hydrogen with the fuel and air mixture you increase the fuel mileage. It cleans the engine, increases the power, decreases emission and decreases dependencies on oil. Hydrogen fuel is not a new concept. It is a 90 year old technology. The hydrogen fuel cell generator produces hydrogen on demand and does not store it.

Easy to install, you will need to mount the unit in the engine compartment. Now add distilled water and baking soda to the unit. Then you will need to hook up a positive fused line to a 12v. keyed source 3 amp draw per fuel cell and a line to a negative source. Next, run a vacuum line to the air intake. No adjustment to the engine is needed.

The seller says that he gets 25 miles per gallon when using them on his truck, compared to 12 miles per gallon without the fuel cells.
