Lancer is correct.. that's a Rupp (Lancer) A-Bone.. narrow hoop means -what was that? 65?- or later.
minus engine is a bummer though...
if it comes with the original wheels (Turbines as you see on the Pic you posted)
the 600 are
almost justified if it's in good unrestored condition.
without wheels, your down to 300 already,
so check the wheels for cracks (cast aluminium... one hard hit and they go)
those are likely the most expensive parts on the whole kart, well since you don't get the original engine.
Oh.. make sure you get the engine mounting plate.
those are pretty hard to find as an original too.
The fully restored perfect condition kart on the Pic you posted
is about a full k depending on demand I'd say anything from 950-1100 as it sits.
I'm not sure.. I think 600 is a lot of money but without seeing the actual kart in question,
I can't tell.
It might as well be a RobRon (recent replicas of the Rupp A-Bone) well made karts, original tooling yadda yadda.. still not as expensive as an original from the 60s

Or worse..
it can be a 70s cheapo replica Clark? (man, my brain isn't serving me well today) they look utterly identical until you measure the thing.
