Lol, it is funny to do some research and find out how many people are still using these both as back up and still use for prime power in remote areas.
We used to make stuff to last, a couple years ago we sold a fully working Farmall M tractor to someone who needed it on their farm. It was built in 1941and was literally a tank! Problem was, it didn't have power "everything" and an air conditioned cab so has gone out of fashion now. :-)
