Bought an oil heater from Monkey Wards that replaced the dipstick, plugged it in to homes 110 V at night so the heater would work on cold mornings driving to work.

Monkey Wards...LOL, I haven’t heard or seen that term in decades...that was what we always called them.
I have a Monkey Wards canister vacuum cleaner from early 1970s in the other room. I bought it for my first apartment when I was 19. Though it’s seen better days (and decades), it still works. Impossible to find proper bags for it, though. The ones they sell you these days claiming to be for that model are all rather generic, and it’s a wrestle to get them to conform. Hence I don’t use it much anymore. Husband doesn’t want to throw it out, just in case we ever need a backup for our modern, bagless Dyson. The latter is a good machine, but unfortunately made of plastic, unlike the MW (which I suspect is a relabeled Eureka), which is all metal.
