Well, it all depends on thae actual S/N, yes? Way early "0L" ought to have those features, whilst a later one might not, it just depends! Spinecracker's example had an early style fore stock, which won't be easy, just for starters.
I'd rather wait and spend more for a nicer one than get frustrated by something that just "ain't right". I've done without this long!
Things like this are highly subjective- what one buyer will pay depends on to many things to give a set price. Even a mood swing can change the "value" 2-300 $ overnight!
