I've seen numerous Brown ranges in manufactured housing units. Usually in the form of a 20" range but also bol 30" in park models as well as older mobile homes from the 60s-80s. After that they made a big deal of selling the fact that they were going with "name brand appliances" such as GE, which it usually is/was.
As for standing pilots, several good points about the problems with it have been made.
Another problem is for those who are not so discerning, are not such good house keepers, and their household fosters other live-in residence that can multiply quickly and are drawn to warm areas for nesting. Standing pilots are perfect for that. Basically the entire range is warm all the time, so is the surrounding cabinets and the area behind and above the range. Having been a landlord, I've seen places where if you turn the oven on, a few minutes later there are bugs running up the walls to get away from the sudden boost of heat.
And standing pilots are not just for stoves. Water heaters still today, and less frequently today, furnaces. Even some pool heaters and gas fireplaces.
A standing pilot in a water heater is still fairly common and not such a safety hazard so long as it's a gravity vented heater. However, I had a situation with a ten year old house I bought in 2005. It had a direct vented water heater, using inside air for combustion. I naturally expected it had an electric ignition. No, it was a standing pilot. So, the fan only runs when the flame comes up to full burn. On pilot there is no fan and there is no vent. Ridiculous. I replaced that.
If you want to know just how much heat a standing pilot gives off, and you have a standard vent gas water heater, try this easy experiment that I purposely chose a while back.
Always wanting to conserve, I put my water heater on vacation setting (pilot only) to see how long the water would stay hot or warm. Now I've done this with an electric water heater, so there is a point of reference.
With the gas water heater on pilot, the water stays warm enough to take a warm shower. It stays warm enough for washing hands. The only time I needed to turn it on full burn was if I was doing the odd load of hot laundry, or something else where I specifically needed a large batch of hot water. For me, that was like once a week for about an hour. The rest of the time, that water heater sucked up the heat given off by just the pilot. So much waste.
We have remember, in the early part of last century, The U.S. was awash in oil and it's bi-products. It was all we could do to burn it up and play with our new toy. And as Americans, void of nearly any common sense, we burned through it and enticed other cultures to do the same.
Now, we're paying the price. So strung out on the stuff, most people don't know anything different. It isn't easy to make the necessary changes. Its really sad.
