The model No. 5 was made between 1907 and 1914 . Yes if you are into Steampunk this could be your typewriter . Information from Wikipedia : This is a The general design of Oliver typewriters remained mostly unchanged throughout the company's history.[11] The Olivers are "down strike" typewriters, meaning the typebars strike the platen (also known as the roller) from above, rather than from below ("up strike") or from the front ("front strike"). Unlike the "up strike" method, which prints text out of sight on the underside of the platen, the "down strike" is a "visible print" design, meaning the full page is visible to the typist as the text is being entered. The relatively greater striking power of the "down strike" design led Olivers to be preferred for specialty uses such as stencil cutting or "manifolding" (copying using carbon paper).[15] The "front strike" method, a competing "visible print" design, was patented around the same time (1889–91), but an effective machine that did not interfere with the typist’s line of sight was not available until 1897 when, roughly three years after the introduction of the Oliver No. 1, the Underwood No. 1 appeared on the market.[16]

The Oliver’s typebars are bent in a bow (forming an inverted "U" shape) and rest in "towers" on the sides of the typewriter. This design limited the machine to a three-row QWERTY keyboard as the typebars were stacked such that they grew progressively larger as more were added. The size and usability implications of adding additional keys and thus, more typebars, precluded the addition of a fourth keyboard row dedicated to numbers.[16] Although a four-row prototype was designed in 1922, it was shelved due to the company’s financial troubles at that time.[4] The No. 20, No. 21 and portable models produced by the British Oliver Typewriter Company had four-row keyboards.
