Unfortunately, lots of strange things are loose in Central Florida. I sold about 100 of the large version from a closed nursery at Renninger's Flea market in Mt Dora about 12 years ago. The antique freaks were buying them by the dozen, to use for decorations.
There's a secondary definition of "smudge" as a noun that is "a smoky fire". Now it's most often used in connection with protecting fruit plantaions from frost, but you'll also find it in woodscraft and outdoorsmanship guides to refer to a fire designed to throw smoke, rather than burn cleanly, either to keep away insects or as a signal.
maker of oil-drilling and brass-fitting equipment in Erie PA, established in 1865. "The principal specialties of the works are malleable iron fittings, oil well supplies, brass work for engine builders, plumbers and steam and gas fitters, which comprehends a vast variety of articles of various styles and sizes."
Groves in Florida spray a fine mist that freezes on the fruit, then harvest and process it as fast as they can, so it doesn't thaw and go bad. I used to live in Lake county, and you KNEW when it dropped to 34 degrees during the night, when all those diesel pumps were fired up.

I had a grove pot for many years that I used to cleanly dispose of used motor oil. If it's tuned correctly, it will burn anything you can vaporize below about 400F, and can be made to burn with a clean blue flame. The grove people used to deliberately make them run rich and smoke, in the belief that the smoke "would hold the heat in".
I grew up in Florida in the 50's and 60's. It was common for school-aged boys to hire out to fuel and re-fuel the pots in the wee hours.
By way of making a smudge when the mosquitos got bad my Dad used to pull the air filter and squirt some oil into the air intake on his lawn tractor. Seemed to work and looked cool as Hell (at least to a 6 year old). Probably wreck the emission control system these days.
