Imperial signet portable manual typewriter, produced in the late 1960s and 1970s. While the Imperial brand was originally a British manufacturer based in Leicester, England, the Signet models from this era were primarily manufactured in Japan by Silver-Seiko after Imperial was acquired by the U.S. conglomerate Litton Industries It was tested as you can see in the picture and it works fine. The cover fixation is missing so he bit loose when transporting but its fine when the machine lays normal position. Fell free to check my other advertisings maybe something else catches your attention.
