This RK Imperator petrol lighter is from Richard Kohn from Vienna, Austria. 1911 was an important year for the development of semi-automatic lighters, Read the stamp as “In d. m. Culturst. ang.” “Cultur” with a C belongs to pre-reform German orthography. The 1901 spelling reform moved such words to K, and usage shifted through the following decade, so a C spelling points to a design registered at the earlier end of that transition. That coincides with the 1911 model date on the lid. Reall nice old petrol lighter.Push button automatic. Monogrammed at the very top with the name Mcdell and the date of 1911. All of the moving parts move as they should when the lighter is opened. There is finish loss and wear as to be expected throughout the item. The lighter has not been serviced or cleaned and is likely more than 100 years old and will require some TLC in order to fire.
