This is why I love working on old machines. Here’s an exploded view of every part of the machine, all numbered, frequently with a symbol and specifications for the parts that are common, off-the shelf fittings that you can buy anywhere. And recently I came across this, which is basically 1950’s manual speak for “if you didn’t buy the motor from us, you might have to do some goofy shit, don’t worry about it.”
