Help identify Old Nintendo System with 15 built in games..

I have a really old Nintendo Entertainment System, it has 15 built in games and one controller

 

Could someone please help me identify it and tell me what the value of this machine is?

 

It's some strange variant of this http://www.slipperybrick.com/2009/01/famicombox-an-nes-with-15-cartridges-built-in/

probably transitional between the famicon and nes.. possibly to use up surplus hardware.. or a working production mockup.. something like that anyway... if it isn't a total pirate thing.

If the controller doesn't unplug then theres a chance it's a Dendy Russian thing/fake/clone whatever.

I can't find it on any lists so it's probably pretty rare.. shame it's so beat up..

I guess there aren't any meaningful stickers or numbers anywhere on it?

 

the controllers do unplug, i did not find any stickers or numbers on it,
