Well it not a Browning or a Mauser and definitely not a 1914. These are the creations of Chinese gunsmiths\blacksmiths. Some are well made others not so much. Yours looks like one of the better quality ones. They liked to put markings on there creations that made them appear to be popular firearms that were imported into China. They are only rare in the since that few were made of any particular design but I don't know anyone who collects them and if someone does it is because they can be bought cheap.
