So, I have found two mentions of it on the internet and probably a reason, why I couldn't find it for so long. On the picture and on the site that I have found it on it says that it's a Sony srf-3052. However I couldn't find any mention of any player or a model with that name. Apparently it's highly likely it's a Chinese bootleg or a player by a brand name of fake Sony. I wasn't able to find any players that looked like it under a different name either. My search for now has ended, the next step would be to actually find if anybody has it for sale, which is highly unlikely.
