Range Hood in 30 years AGO

I already live in this house more than a year.Besides my landlords went back China last time,I merely step into kitchen.Today I found a indifferent thing---see the real look of the range hood in my kitchen FINALLY!!!Don't think I am 'siao'..Since I moved in,the range hood just wrapped by cling wrap and I never got chance why.I guess they took the cling wrap off is because they wanna replace a new range hood.Then they can sell this unit for the higher price(haih...headache when I think of this).I heard that this unit already 30++ years so means that the range hood also 30++ years old lo...Have you see the 30 years Range Hood??

See the button can guess its age...

The most classic is the engine lo...haha
