Trying to identify a mystery set, mostly black and dark grey
I don't know if that is a cohesive set, but all the parts scream 2005 era Star Wars.
There is a x-wing canopy that gives me that idea, but the real smoking gun is the color combination of parts. There appears to be a lot of old (warm) dark grey, prior to Lego changing to the more (cool) bley they use today.
I think its just stray parts from that era. Enjoy all that classic dark grey, its great for mixing in with modern greys.
