I found a WW1 era Model T garage that has a couple untouched remnants about 90 years later, the fan belt hangers, belt measure tool, speaker, and first aid kit. This isn't a museum.

The hanger stretches for 20 or 30 feet on a rafter. Every hanger still has it's own part number tag, dusty and dirty, but original and untouched, stapled to the Gates brand hanger

it has the words Gates V belt Length Finder across the crown

the First Aid Kit has it's roots in the railroad industry. As the story goes, Johnson & Johnson co-founder, Robert Wood Johnson, was on a train trip through the Rockies where the railroad was is in the midst of major construction and expansion. Johnson happened across the railroad's surgeon and witnessed the injuries and safety issues they faced. The result was a letter sent by Johnson in 1888 to railroad surgeons around the country. To quote:

"We are about to get up a railway emergency case, and wish to make one that will be of real service in the field it is intended for…it is our wish to get suggestions from practical railroad surgeons. We already have them from one of two of the surgeons of the largest western railroads."

By1890, Johnson & Johnson began offering what was known as the "Railway Station and Factory Supply Case". Further refinement of the package soon led to development and introduction of the venerable Band Aid brand of adhesive bandages that we still use to this day.

Does anyone recognize the symbol on the speaker fabric?

How incredible is it that no one has screwed with these artifacts in 8 or 9 decades! ? !
