NOS stands for New Old Stock & NIB is New In Box.
That means that it is still new [unused, perhaps still in it's original box as these carbs are] but it is old stock. Stuff that has remained unsold since it was bought in by whoever still has it.
A part may have laid on the shelf for thirty years, so it is NOS.
NOS parts can be genuine, or non-genuine [sometimes called 'pattern parts'] so please, do not go off the handle because something is NOS. These carburettors were supplied to Nissan by an outside specialist manufacturer, in this case it was Hitachi & these outside suppliers are known as Vendors. Large percentages of many cars are provided by vendors. The car maker may make the engine, but vendors usually supply the gaskets & seals, distributors, starters, altenators, timing chains, bearings, pistons & rings, & many other parts, & thats just the engine, so 'genuine' does not necessarily mean that it was made by the car maker. They even use multiple vendors for some parts on the same car during it's production run. Datsun used both Nabco & Tokiko to supply brake parts for B10 & B110's.
Now, if these carbs came from a carb specialist shop, but were supplied direct from Hitachi back in the 70's, does this make them inferior?
Of course not, & while we're at it, just because something is non-genuine, doesn't automaticly mean that it's inferior. If something is inferior it is because it is substandard in design, material or workmanship, & this kind of part can come in 'genuine' boxes too.
By way of example, both Holley & Carter made a range of 'replacement' carburettors for popular US cars. If your old carb became unserviceable & uneconomic to repair, both companies had a nice new 'non genuine' replacement that would fit & work just as good as the original. Maybe even better. Non genuine does not necessarily mean inferior.
NOS is just that, still unused, but old stock. Nothing more.
