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

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! ? !
