Guys - I've been offered a trade for a Norinco SKS D.  

I'm ignorant on what I need to look for to ascertain authenticity of the factory D designation.  

This rifle in question has a 20" barrel and a bayonet which set off red flags right away.  The price also seemed high.  

What do I look for to make sure this isn't some converted frankengun, and what's the going rate?  

Thanks,

I'd be interested if you don't take it... email me if you don't.
