The Seagull DF-300 is a SLR camera body with Minolta SR-bayonet mount. It can be used with most of the lenses which are made for Minolta's manual focus SLRs. On the back it is marked "Shanghai China, licensed by Minolta". It's a licensed copy of Minolta's X-300 which was produced in the same Shanghai General Camera Factory. Name variants branded Safari, Centon, and Carena were also sold, and the Vivitar V50 seems to be the same camera, as well as Soligor's SR-300 MD.
It was released in three different versions. The basic black and silver version, an all black-bodied version and a limited edition named "Seagull DF-300x," of which only 1000 were made to commemorate Hong Kong's return to China in 1997. Each set was comprised of a camera body and lens with matching serial numbers, with "Commemorating Return of Hong Kong" on both camera body and lens being written in Chinese. According to the company's website, it looks like the Seagull DF-300x is still being produced, in a regular edition, as of August 2017. 
There is also an updated version of the Seagull DF-300 which features the bigger handgrip on the front and one added to the rear, where earlier ones had no handgrip.
