Not sure how you’d know what set I meant when I sold it several years ago…

So I’d recommend 50% off what you’re trying to get. Sometimes sets just don’t
sell for no apparent reason too. I’ve had a complete set listed as the cheapest
in the world and it sat over 2 years while others sold that were more expensive.
I think I know the set you're referring to, and all but one of those sales
was less than yours. I think in this particular instance people are willing
to hold out. Just a hunch really.
As for the OP, with all the stuff that is missing, I think you basically have
an assembly of relatively common black bricks. The 150 price suggestion from
others seems pretty fair.
