I've a few separate machines on the operating table as of the moment, and thought that I would see how well the Typosphere knows the random bits and pieces of the innumerable machine makes and models out there.
Clearly a key lever. But from what machine did this come from?
Of all the machines which I've taken down to pieces to clean and restore, this particular machine has by far the most unique type-bar design.
Another type-bar, but with its own unique twist; This type-bar is only about 2 and a half inches in length.
A switch with a balled top. A curious feature that not many typewriters often use. This is looking at it as if you were peering from the inside of the machine outwards.
