I have a couple of Lasko ? 20" box fans, made in the US, that I've been using for years. Fan blade is plastic, housing is metal. I had this old metal fan on a stand my dad bought when we were kids, late 60s or early 70s, it probably died 6-7 years ago.It had a 3 speed pushbutton switch: last use I pushed the button, I got shocked.It went to the scrap bin. In the mid-90s it woke my then-GF and I up with a knocking noise. I found an oil tube and filled it with CLP, problem solved. GF asked what I did, I told her, she said "why do you have gun oil?" I asked her "doesn't everyone have gun oil?"
